Receiving A Call - Simoco SDP660 User Manual

SDP660 – USER MANUAL
In most systems, it is good practice to wait a short time (0.5 secs) between pressing the PTT
switch and commencing to speak. This allows the transmission path to be properly established (or
not) and avoids lost or distorted speech.
On some channels, the radio may provide alert tones to indicate the success or failure of the
establishment of the transmission path. Only speak after the tone indicating the transmission's
successful establishment. The radio's LED will also turn
and the display will also show the relevant transmission icon.
Use the correct operating procedure and keep transmissions as short as possible.
Release the PTT switch as soon as you have completed your message in order to hear any
replies. The radio cannot listen and talk to groups simultaneously.
If you wish to talk to other groups or individuals these can be selected on the contact menu or
dialled before pressing the PTT.
Note.
A Transmit Limit Timer may be setup that limits a continuous transmission on a
channel. The last 10 seconds before the timer expires may be accompanied by
warning beeps.
