Operation with Standard Features
Operation with Standard Features
To fit your particular needs, a number of features are avail-
able to enhance the operation of your GP300 radio. These
capability features are described for you in this section.
Time-Out-Timer
The Time-Out-Timer (T.O.T.) feature alerts you if the trans-
mitter is keyed for a long period. This feature prevents chan-
nel tie-up and excess battery drain in case of an inadvertent
keying of the transmitter. The radio operates normally in the
receive mode with the T.O.T. feature. However, in the trans-
mit mode, a single transmission (uninterrupted depression
of the PTT) "times-out" after 60 seconds and the radio
reverts back to the receive mode, even with the PTT button
remaining depressed. After the 60 second time out, a con-
tinuous alert tone is generated in the receive mode until the
PTT button is released.
Volume Set
Pressing one of the side but-
tons will initiate the volume
set feature, if it has been
programmed to perform this
function. The radio has the
ability to monitor the current
radio volume level whenever
this button is pressed.
"White noise" will be present
for the duration of the button
press that indicates the cur-
rent level setting of the vol-
ume control.
