2-16 FEATURES AND BENEFITS
The Squelch feature uses a threshold value to determine whether a received signal is strong
enough to produce a clear communication; if the signal strength exceeds the threshold , the radio
unmutes. The radio can be programmed to allow the user to change this threshold value between:
■
■
Normal Squelch : to be used under normal operating conditions, where channel noise levels
are low.
■
■
Tight Squelch : selecting tight Squelch increase the Squelch threshold value. This means that
only the strongest signals will cause the speaker to unmute. Tight Squelch should be enabled
when channel noise signals are sufÞciently strong to cause the speaker to unmute while
Normal Squelch is selected.
The radio user can toggle between Normal and Tight Squelch by using either the programmable
side buttons or the menu and navigation keys.
The Monitor function bypasses the Squelch setting and allows the radio user to listen to all channel
activity.
3.4.3 Mute/Unmute Rules
Using the CPS, it is possible to programme the P Series radios with different mute/unmute rules.
This allows you to match the radios to your customer's speciÞc requirements.
The CPS allows you to select, on a per-channel basis, the rule that the radio uses to open and close
its speaker. The choice of rules is:
Note : These Mute/Unmute rules are only available when the speciÞc radio personality has its
Receive Squelch Type set to TPL or PL.
3.4.4 Monitor
The Monitor function increases the effectiveness of your customer's communication system by
allowing the radio user to listen to the communication channel before transmitting. The user is
therefore able to ensure that she only transmits during a quiet period and avoids interrupting any
ongoing conversations involving other workers.
This function is particularly useful on a PL system, where several different groups of workers share
the same channel. The Monitor function bypasses the PL squelch Þlter and allows all conversations
on the channel to be heard.
The Monitor function can be assigned to one of the programmable side buttons - all channel activity
is heard as long as the appropriate side button is pressed.
