You may also use this feature to try to prevent potential interference by
following the below steps:
•
Power down the CT-711 transmitter by pressing and holding the power button
until the LCD screen appears blank
•
Ensure that the CR-711 receiver is powered up
•
Press and release the SET button four times to enter the channel/frequency
scanning menu
•
Press and release either the up or down button
•
The receiver will automatically scan through all unlocked channels
•
If the receiver does not detect any transmission signals, it will return to the
default screen
• If the receiver does detect a transmission signal, it will stop scrolling at the first
signal it detects. As an example, the receiver detected a signal on
Channel 001 (625.000 MHz) and the following display appeared on the
LCD screen:
This means that someone within 100 feet (30 meters) is operating equipment
at 625.000 MHz.
If this is the case, it is important that you do not operate the RFS 700 system on
this channel/frequency (Channel 001/625.000 MHz in this example), as you will
most likely experience interference.
You may even want to lock out this channel/frequency on both the
CT-711 transmitter and CR-711 receiver to ensure that no one accidentally
accesses this channel/frequency. (See page 16 for instructions on locking
and unlocking channels/frequencies.)
•
It is recommended that if your CR-711 receiver does detect a signal, you
return to the channel/frequency scanning menu and perform the scan again
until the receiver has scrolled through all unlocked channels.
Enable or disable auto-off
Press and release the SET button six times to enter the auto-off menu. The
following display will appear on the LCD screen as the default auto-off menu
when the CR-711 receiver arrives to you brand new.
Press and release the up or down button to replace the word “DISABLE” with
the word “ENABLE” as illustrated below:
If you choose to enable the auto-off feature, the CR-711 receiver will power
down if it does not receive a transmission signal from the transmitter for
approximately five minutes.
Once you have selected “ENABLE” or “DISABLE” from the auto-off menu,
release all buttons until the LCD screen shows the default display:
