Channel 16 Safety operation
On-Site Channel 16 on your radio has been optimized for the following functions:
Lone worker - This safety feature requires the user to press any button on the radio at
least once every 15 minutes� Failure to do so will send an emergency alert tone over the
radio channel� A warning tone is sounded 15 seconds beforehand to remind the user to
momentarily press a button� On channel 16 on the GTR model it is automatically ON and
the LED will flash RED to indicate Lone worker mode. To disable Lone worker press the (C)
button for 3 seconds� Press for another 3 seconds to re-enable� The GT model requires
you to manually activate� Press for 3 seconds to enable, another 3 seconds to disable�
Emergency call - enabled when a user presses the Orange button (A) for 3 seconds�
The radio will automatically change to channel 16 and it will initiate an Emergency Call�
Three emergency calls will go out followed by Auto Tx�
Auto Tx - Automatically enabled when Emergency is triggered so that others can re-
motely monitor local user audio in the event of an emergency or a lone worker failing to
respond� The radio will automatically transmit audio for 10 seconds and then receive for
10 seconds� the cycle repeats 3 times�
For a small nominal charge, the radio can be programmed to send its individual elec-
tronic ID so that it shows on a display unit� These Safety channel function can be best
experienced by use of a GTR radio as the LCD display can show the unit’s identification
when programmed�
Alternate Programming
The GTR and GT series radios can be programmed with a vast variety of the features�
Some of which are listed in the following pages� If you feel they may allow you to make
better use of your radios, then contact your dealer to discuss� They will be happy to
discuss your specific application and then arrange the required re-programming for a
nominal charge�
