Functions and operations
Squelch level (SQL) - MENU No.0
Thanks to this function you can adjust the squelch in 10 different levels:
•
level 0:
opened squelch. With this setting, CT590 will detect all signals,
also the weakest ones, but will also receive the background noise or unde-
sired signals.
•
levels 1- 9:
level 1 (lowest squelch level), level 9 (highest squelch level).
If the squelch is set to the highest level, the radio will receive the strongest
signals only.
Step frequency (STEP) - MENU No.1
This function lets you select the desired frequency step.
The selectable steps are the following:
2.5/5/6.25/10.0/12.5/25 KHz
Note: in channel mode, this function cannot be modified.
Output power (TXP) - MENU No.2
In this
MENU
you can select the high/low output power.

Note: select the output power can improve the quality of the call, while the low
output power can reduce the radiation and the battery capacity loss. In channel
mode press the fast key “#” to switch between the high or low output power.
