•
Push-To-Talk Delay (ms)
after a keying event, which must expire before the radio is
allowed to transmit. The allowable range is 0 to 255 ms, with the
default being 0.
•
Clear-To-Send Delay (ms)
between when an RTS (ready-to-send) signal is received and
when the CTS (clear-to-send) signal is returned. The allowable
range is 0 to 255 ms, and the default is 0.
•
Automatic Freq. Correction
(AFC), is used to counteract the slight RF frequency drift that
may occur over time or through wide swings of ambient temper-
ature.
•
Switched Carrier (B Modems)
for use on radios with "B" modem suffixes, and only applies to
remote radios. ("B" modems are intended for compatibility with
earlier MDS x710 radios.) In some networks, the master unit is
not keyed continuously, and transmits only when it has data to
send to remotes. This is known as Switched Carrier operation. In
such a network, the remote radios should have the Switched Car-
rier setting turned . The default setting is
ON

kept off when working with normal or weak signal levels.
