EVX-5400 OpErating Manual

Transmit 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 sec-

onds before time-out. Another beep will sound just before the deadline; the red “

”

indicator will disappear and transmission will cease soon thereafter. To resume

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 operating function/feature change or inadvertent

transmission, various aspects of the front panel’s keys may be locked out.

To activate the Locking feature, press and hold in the

[

]

key while turning the

radio on. To disable the Locking feature, repeat this power-on procedure.
