BASIC OPERATION OF THE TRANSCEIVER
Automatic Time-Out Timer
If the selected channel has been programmed for automatic time-out, you must limit the length of each transmission. While transmitting, a beep will sound 10 seconds before time-out. Another beep will sound just before the deadline; the red “TX” indicator will disappear and transmission will cease soon thereafter. To re- sume transmitting, you must release the PTT switch and wait for the “penalty timer” to expire (if you press the PTT switch before this timer expires, the timer restarts, and you will have to wait another “penalty” period)
Key Lock
In order to prevent accidental frequency change or inadvertent transmission, various aspects of the VX-2100E’s keys may be locked out.
To activate the Locking feature, press and hold in the [P1] key while turning the radio on. To disable the Locking feature, repeat this power-on procedure.
ADVANCED OPERATION
Programmable Function (PF) Buttons
The VX-2100ESeries includes six Programmable Function (PF) Buttons. The PF button functions can be customized, via programming by your VERTEX STAN- DARD dealer, to meet your communications/network requirements. Some features may require the purchase and installation of optional internal accessories. The pos- sible PF button programming features are illustrated below, and these functions are explained on the pages to follow.
