3 On/Off Problems
•
Try to switch the phone on with its battery.
•
If the phone starts with its battery, switch it off and connect a charger in the system
connector.
If the phone starts with the charger, there are probably no On/Off problems with it.
If the phone does not start with the charger, see chapter Capacity/Charging Problems.
•
If the phone does not start with its battery, connect a charger in the system connector.
If the phone starts with charger (illumination and display turn on) and indicate charging
check the keyboard and the dome switch for malfunction (Fig. 1). If necessary, replace
the keyboard and/or the dome assembly or handle the unit on according to the local
company directives.
If the phone does not start with the charger but indicate charging (red top diode lights) the
battery is probably deeply discharged. After 1- 15 minutes of charging the phone is
supposed to start (illumination and display turns on). Charge the battery fully.
If the phone does not start (illumination and display does not turn on) after 15 minutes or
if the phone does not start with the charger and does not indicate charging, take out the
battery.
Check that the battery contact surface is free from dust/dirt and mechanical damage
(Fig.2 ). Clean the battery contacts surface if necessary.
Check the battery connector for dirt/mechanical damage (Fig. 3). If necessary, clean or
replace the battery connector.
Put the battery back in the phone, connect a charger in the system connector and try
again.
If the fault remains replace the battery to one with known function and start from
beginning (Try to switch on the phone...).
•
Make a general visual inspection for corrosion or oxidation from liquid damage. No
further action should be taken for a liquid damaged phone. Handle the unit on according
to the local company directives.
•
If the fault remains, try to upgrade the phone with the latest software.
•
If the fault still remains, handle the unit on according to the local company directives.
