Remote Control
Unpairing (Disabling) an IR Remote from an NVR:
To unpair an IR Remote from an NVR so that the unit cannot control any NVR functions, proceed as
follows:
Press the <DEV> key on the IR Remote. Any existing Device ID# will be erased from the unit's memory
and it will no longer function with the NVR.
Note:
(Re)-enabling the IR Remote requires pairing to an NVR. See "Pairing the IR Remote to a Specific NVR
(optional)," above.
The keys on the remote control closely resemble the ones on the front panel.
