Do not change the frequency of your device without
reason. Apart from the fact that it may not communicate with the
network anymore, you may also violate the applicable radio-
communications laws in your country. Depending on the
destination country, some models may also return an error
message when trying to use this command.

RSSI
A720, A720B, A723
Sets/returns the Relative Signal Strength Indicator threshold at
which an RF receiver must wake up.
The threshold value. For the A720 family, it can take values from 0
to 255; it is typically factory set to 58. For the A723, it typically fac-
tory set to 42.
The instant RSSI value and the programmed threshold.
The factory default is set to 58 units. The RSSI threshold is used to
detect if any radio activity is on the channel. The value set must be
approximately 30% higher than the actual measured value when
no signal is present on the channel. To measure the actual value,
use the command RSSI with no variables or parameters.
