Operation
In operation, the Commander GSM operates in exactly the same manner as any
hard-wired tough phone.
To make a call
1 Lift the handset and wait for the dial tone.
Note: With the zero button keypad option lifting the handset out of the cradle
will automatically dial a pre-determined number.
See Appendix A for details on how to program the auto-dial telephone number.
2 Where a keypad is fitted, dial the required phone number or press the
appropriate memory button (depending on which keypad option is fitted).
A short while after the final digit is pressed, the phone will attempt to place the
call.
3 Where a fully featured keypad is fitted:
• Press the ‘LR’ (Last number re-dial) button to automatically call the last
number dialled.
• During a call, press the ‘S’ button to mute the handset microphone.
Press the ‘S’ button again to enable the microphone.
Once the handset is replaced, it will automatically remove the microphone
mute ready for the next call.
•
Note: The ‘R’ button is reserved for future functionality.
Off-hook timeout
If you do not replace the handset on the hook (when not in an active call), the dial-
tone will cease after 150 seconds and the phone will enter a low-power idle state.
The phone can still receive calls and SMS commands.
To end a call
• Replace the handset on the cradle hook.
To receive a call
• When the ringer sounds, lift the handset and speak to the caller.
