Operating states of the phone
•
On
- The phone is fully powered and ready to make and receive calls.
•
Charge only
- This is the state that the phone will enter when external DC
power is applied. If power is removed, the phone will enter the “Off” state.
•
Off
- This is the state in which the phone is shipped from the factory.
To switch on
If the phone is “Off” and has sufficient battery power or is in “Charge only” mode,
pressing the on/off pushbutton will put the phone into the “On” state. The “On”
state is remembered, regardless of the amount of charge in the battery or the
availability of DC supply.
If the ERROR indicator is flashing Short/Slow, leave the external DC power con
-
nected to fully charge the battery, or at least until the ERROR indicator stops
flashing.
Note: to fully charge the battery may take in excess of 5 hours depending on the
current charge state of the battery.
If the phone is “On” and the battery charge becomes exhausted, the phone will
turn off. Once the external DC supply is restored, the phone will automatically
enter the “On” state and also start charging the battery.
Indicator power saving
To save power, the internal indicators will not be lit after five minutes of idle (no
incoming or outgoing calls). To reactivate the indicators, momentarily take the
handset off hook and the five minute timer will be restarted.
To switch off
If the phone is to be shipped, stored, or the SIM changed, press and hold the
pushbutton until the FUNCTION and ERROR indicators extinguish. The phone will
now be in the
Off
(Charge Only)
state.
Note: If the phone is to be shipped or stored, disconnect the internal battery and
ringer connections between the case front and rear sections. Then carefully place
the front casing onto the rear, taking care not to trap any of the internal cables.
