1.4 Remote Control
The NVR may also be controlled with the included IR remote control, shown in 0.
Note:
Batteries (2×AAA) must be installed before operation.
The IR Remote is set at the factory to control the NVR (using default Device ID# 255) without
any additional steps. Device ID# 255 is the default universal device identification number
shared by the NVRs. You may also pair an IR Remote to a specific NVR by changing the
Device ID#, as follows:
Pairing (Enabling) the IR Remote to a Specific DVR (optional):
You can pair an IR Remote to a specific private DVR by creating a user-defined Device ID#.
This feature is useful when using multiple IR Remotes and DVRs.
On the DVR:
Steps:
1. Go to General > More Settings.
2. Type a number (255 digits maximum) into the <Device No.> field.
3. On the IR Remote:
4. Press the <DEV> button.
5. Use the Number buttons to enter the <Device ID#> that was entered into the DVR.
6. Press the <Enter> button to accept the new <Device ID#>.

Remote Control
Unpairing (Disabling) an IR Remote from a DVR:
To unpair an IR Remote from a DVR so that the unit cannot control any DVR 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 DVR.
Note:
(Re)-enabling the IR Remote requires pairing to a DVR. See “Pairing the IR Remote to a Specific
DVR (optional),” above.
The keys on the remote control closely resemble the ones on the front panel.

Troubleshooting the Remote Control:
Note:
Make sure that you installed the batteries properly in the remote control. You also have to aim
the remote control at the IR receiver in the front panel.
If there is no response after you press any button on the remote control, follow the procedure
below to troubleshoot.
Steps:
1. Go to Menu > Settings > General > More Settings by operating the front control panel or the
mouse.
N/A
Switch between Play and Reverse Play in the <Playback>
mode.
Cycle through tab pages.
Switch between channels in the Synchronous <Playback>
mode.
7. Check and remember the <NVR ID#>. The default <ID#> is <255>. This <ID#> is valid for
all of the IR remote controls.
8. Press the <DEV> button on the remote control.
9. Enter the <NVR ID#> you set in step 2.
10. Press the <ENTER> button on the remote control.
If the Status indicator on the front panel turns blue, then 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:
‒ Batteries are installed correctly and the polarities of the batteries are not reversed.
‒ Batteries are fresh and not out of charge.
‒ The IR receiver is not obstructed.
‒ No fluorescent lamp is used nearby.

If the remote control still cannot function properly, please change the remote control and try
again or contact the device provider.

1.5 USB Mouse
A regular 3-button (Left/Right/Scroll-wheel) USB mouse can also be used with this NVR. To
use a USB mouse:
Steps:
1. Plug the USB mouse into one of the USB interfaces on the front panel of the NVR.
2. The mouse should automatically be detected. If, in a rare case, the mouse is not detected,
the possible reason may be that the two devices are not compatible, please refer to the
recommended device list from your provider.
