Honeywell CK3R and CK3X troubleshooting guide: errors, faults and fixes

Short answer: According to the Honeywell manual, an amber battery light signals a battery error: battery missing, faulty or outside the charging temperature range. Bring the mobile computer back to room temperature, reinstall the battery or try another one.

Likely cause

The light table in the CK3R/CK3X manual associates amber with three causes: battery missing, battery faulty or temperature outside the charging range. Charging resumes by itself when the temperature returns to within the range.

Caution: The manual warns that a mistreated battery can cause a fire or a chemical burn: do not disassemble it, do not heat it above 100 °C and do not incinerate it.

What to do

1. Check the temperature: the data sheet and the battery section of the manual give charging between +5 °C and +35 °C, while the light table in the manual and the AB17/AB18 battery information sheet indicate 0 °C to +45 °C. Preferably recharge between +5 °C and +35 °C.
2. Let the mobile computer return to room temperature: charging resumes automatically.
3. Remove and reinstall the battery: insert the top first, then press firmly on the bottom until the latch clicks.
4. Try another charged battery of a model intended for the mobile computer (AB17, AB18 or 1001AB01).

When to call a technician: if the light stays amber with another battery at the right temperature: contact product support (in the United States and Canada, the manual gives 1-800-755-5505; elsewhere, contact your local representative).

Short answer: According to Honeywell, the battery is very low and the mobile computer will have to go into sleep mode. Connect external power, or save your work, hibernate and replace the battery with a charged one.

Likely cause

The light table in the manual associates flashing red with a very low battery. The title bar then shows the low battery icon (replace soon) or the very low battery icon (replace now).

What to do

1. Save your data and close the applications.
2. Place the mobile computer in a powered cradle or charger, or connect the external power supply.
3. Otherwise, hibernate and change the battery: see changing the battery.
4. Monitor the level with the battery icon in the title bar or in Intermec Dashboard.
5. Do not confuse this with solid red, which simply signals a battery charging on the charger.

Short answer: According to the Honeywell manual, a flashing red Good Read light signals a bad read: the barcode was not decoded. Check that the symbology is enabled in Intermec Settings and that the beam covers the whole barcode.

Likely cause

The light table distinguishes solid green (good read), flashing red (bad read) and flashing green (data collection engine processing or starting up).

What to do

1. Scan again, covering the whole barcode with the beam.
2. Check in Intermec Settings that the barcode's symbology is enabled.
3. Adapt the imager mode to the environment (bright light, reflective surface): see the mobile computer does not scan.
4. If the light is flashing green, wait for the data collection engine to finish starting up before scanning.

Short answer: According to the manual, a flashing blue Ready-to-Work light signals that the ITE terminal emulator is running but is not connected to the host: the mobile computer is then deemed “unhealthy”. Check the Wi-Fi connection and the availability of the server.

Likely cause

The Ready-to-Work light is solid blue when ITE (Intermec Terminal Emulator) is running and connected to the host, flashing blue when ITE is running without a connection, and off when ITE is not installed or not running, the mobile computer then being considered operational. Without ITE, this behaviour can be configured differently.

What to do

1. Check that the Wi-Fi radio is turned on and connected: see the mobile computer does not connect to Wi-Fi.
2. If the network uses WPA or 802.1x, re-authentication may be required when the mobile computer wakes up.
3. Check with your IT department that the host (emulation server) is reachable.
4. Once the ITE session has reconnected, the light returns to solid blue.

Short answer: Check in Intermec Settings that the barcode's symbology is enabled and that the imager mode is suitable (bright light, reflective surface). At less than 30 cm, aim slightly to the right of the centre of the barcode; beyond that, aim at the middle, covering the whole barcode.

Likely cause

According to the manual, you should enable only the symbologies you need and choose a suitable imager mode: 1D Only, 1D and 2D Standard (default), 1D and 2D Bright Environment or 1D and 2D Reflective Surface. The CK3R uses the EA31 imager, the CK3X the EA30, EX25 or 5603ER.

Caution: According to the compliance insert, the CK3R and CK3X are Class 2 laser products (IEC 60825-1, 1 mW maximum, 630 to 680 nm). The device has no user adjustments, and procedures other than those specified may result in exposure to hazardous laser light.

What to do

1. In Intermec Settings, enable the symbology of the barcode to be scanned, and only those you need.
2. Choose the imager mode: 1D and 2D Bright Environment in bright light, 1D and 2D Reflective Surface on a shiny surface.
3. Point the imager at the barcode and hold the mobile computer still, a few centimetres away.
4. Press the Scan button or the handle trigger: the illumination beam, the laser pointer or the aiming frame appears.
5. At 30 cm or less, aim slightly to the right of the centre of the barcode; at 30 cm or more, aim at the middle. The beam must cover the whole barcode.
6. Release the button: a good read is signalled by a high beep and the Good Read light coming on briefly.

Short answer: According to the Honeywell manual, the 802.11 Wi-Fi radio is disabled by default. Enable it in Intermec Settings > Communications > 802.11 Radio > Radio Enabled, then configure the network and security (Funk by default, or Microsoft).

Likely cause

The manual states that the 802.11 radio is disabled by default, with Funk security and DHCP as the default settings. According to the data sheets, the CK3R only supports the 2.4 GHz band (802.11 b/g/n), whereas the CK3X is dual-band (802.11 a/b/g/n), provided that both bands are enabled.

What to do

1. Open Start > Settings > System > Intermec Settings.
2. Go to Communications > 802.11 Radio, tick Radio Enabled and tap OK.
3. CK3X: in Radio Bands, choose a/b/g (2.4 and 5.0 GHz) to enable both bands.
4. Configure the network settings, then the 802.11 security: with Funk, up to four profiles, named in Profile Label and selected in Active Profile.
5. To switch to Microsoft security: Communications > 802.11 Radio > Security Choice, choose Microsoft Security and tap Yes to save and restart.
6. After waking from sleep, WPA or 802.1x re-authentication may be required.

According to the data sheets, the Wi-Fi on the CK3R and CK3X supports WPA, WPA2, 802.1x and CCXv4.

Short answer: In the cradle, the battery light should be solid red (charging), then flashing green (60 to 95%) and solid green (over 95%). If it stays off, the mobile computer is not receiving power; if it is amber, the battery is in error or outside the temperature range.

Likely cause

According to the manual, a battery light that is off means that the mobile computer is not on external power. The compliance insert requires charging only with the intended chargers, cradles and adapters, and with a UL-listed 5 V DC, 2 A power supply approved by Intermec.

Caution: The CK3R/CK3X compliance insert warns that “using the wrong charger could constitute a risk of fire or explosion”.

What to do

1. Check that the cradle (AD20, AD21, AD22, AV10) or the charger is powered and that the mobile computer is properly seated.
2. Watch the battery light: solid red = charging; flashing green = 60 to 95%; solid green = over 95%.
3. If the light is amber, see amber battery light.
4. To charge a battery on its own, use the AC20 quad charger, the AD20 cradle or the FlexDock 1002UC02 cup on a DX2 or DX4 base.
5. Use only a UL-listed 5 V DC, 2 A power supply approved by Intermec.

Pulsing green (60 to 95%) only appears if this mode has been selected in Intermec Settings.
