Problem Causes and Solutions
Telephone will not
switch on
Check that the battery pack is fully charged and correctly
connected to the telephone.
Short battery life Battery life is affected by the network you are using and the
condition of the battery pack.
The life of the battery pack is affected by improper charging,
this is inherent in all Ni-MH batteries. To maintain maximum
performance always use until the low battery warning and then
fully recharge the battery pack. To revive the battery pack use
the telephone until it switches off and then fully recharge three
times. However, the battery pack will eventually wear out and
must be replaced with a new one.
Battery level
indicator ( H )
does not light
when charging
If a battery is deeply discharged it will take a short time before
there is sufficient power in the telephone to light the battery
level indicator ( H ).
The battery pack must be charged in a temperature no lower
than +5°C and no higher than +35°C.
Calls cannot be
made
Calls cannot be made when the telephone is locked (Menu:
Security/Mobile Lock) or outgoing calls are barred (Menu: Call
Bar).
Check that the telephone is registered to a network. Move to a
coverage area and operate your telephone after it has registered
with a network.
