Tips and Tricks
•
A C960 system in a location with a 900 MHz cordless phone can experience loss of communication. We
recommend that you don’t use a 900 MHz phone near a C960 Intercom System. If there is no choice, and
interference is encountered, change channels on the Base Station to one at least three channels away. It may
be necessary to go further than three channels away. Lane 2 frequencies are also available.
Most modern 900 MHz cordless phones should be smart enough to select an unused channel on which to
operate. One thing to try which might be a solution if the phone is “smart” is to:
ü
Turn off the power switch on the portable phone handset.
ü
Hang up the phone.
ü
Unplug it from the power line.
ü
Turn on the C960 and hold down the talk switch (while doing the next two steps).
ü
Plug the phone back in and take it off hook.
ü
Turn on its power switch.
If the phone is “smart”, it will see that the talk and listen frequencies of the C960 are busy and go to some
other channel.
