If there is no response after you press any button on the remote, follow the procedure below to troubleshoot.
Steps:

User Manual of 87P Series NVR
17
1. Go to Menu > Settings > General > More Settings by operating the front control panel or the mouse.
2. Check and remember NVR ID#. The default ID# is 255. This ID# is valid for all the IR remote controls.
3. Press the DEV button on the remote control.
4. Enter the NVR ID# you set in step 2.
5. Press the ENTER button on the remote.
If the Status indicator on the front panel turns blue, the remote control is operating properly. If the Status
indicator does not turn blue and there is still no response from the remote, please check the following:
1. Batteries are installed correctly and the polarities of the batteries are not reversed.
2. Batteries are fresh and not out of charge.
3. IR receiver is not obstructed.
If the remote still can’t function properly, please change a remote and try again, or contact the device provider.
