3. Remove any dirt from the unit using a stiff, non-metallic, short-bristled brush.
4. Wipe and dry the unit with a soft, absorbent, lint-free cloth. Make sure that there are no damp
spots on the connectors or in cracks and crevices.
5.5 Mechanical and Electrical Checks
Before conducting more complex tests, clean and check the unit for any mechanical defects that
might cause or contribute to the problem.
The following tests constitute the mechanical and electrical consistency of the unit:
• Shock and Pressure
• SIM Card Swap
• Accessory Swap
• Lockup
• Battery Connections
• GPS Receiver
• Voltage Recognition
The Shock and Pressure test time is approximately 3 minutes:
1. Power up the unit.
2. Throw the unit into the palm of your hand alternating the front, sides, and back of the unit.
Check if the unit turns off, displays “Reset,” or status LED (if so equipped) turns to red. Then,
continue to the next step.
3. Apply pressure to the front, sides, and back of the unit with your thumbs. Never apply direct
pressure to any display or lens area.
If unit turns off, displays “Reset,” or status LED (if so equipped) turns to red, retry this test with
a battery known to be in good working condition. Verify that the contacts in the unit and on the
battery are clean.
4. Start test again. If the reset/intermittent contact condition persists, power down the unit and send
to your iDEN Customer Support Center.
5.5.1 SIM Card Swap Test
Use this test to determine if the SIM card is defective, or if the unit is defective.
The SIM Card Swap test time is approximately 5 minutes:
1. Power off the unit, and then remove the battery.
2. Remove the SIM card from the unit.
3. Clean the SIM card, if necessary, by wiping its surfaces with a clean, static-free cloth, and then
check the contact areas in the unit for foreign material, damage, or other defects.
