The remote control allows users to:
Answer and end calls
Adjust the call volume
Mute and unmute the call
Note: The remote control cannot be used to start a call.
Using the remote control
To operate correctly, the remote control for the HDL200 system needs to be pointed at the center of the LCD screen, where the infrared sensor is located (the infrared sensor itself is not visible). The sensitivity of the infrared detection drops off when the angle approaches within 45 degrees to the front surface of the HDL200 system, although the remote control will work at 25–30 degrees in most instances. The optimal range for the remote control is 20' (6.1 m). The maximum range is 30' (9.1 m).
If the HDL200 system is not responding to the remote control at this range, consider replacing the batteries.
Call answer and call end
When the HDL200 system remote control call answer or call end (hang-up) button is pressed, the remote control sends a command to the computer, which will be interpreted by the UC&C application and the call will be answered or ended.
Note: The call answer and end buttons are not compatible with some platforms, such Webex and GoTo Meeting.
Mute button and indicator
When the HDL200 remote control Mute button is pressed, the remote control will send a command to the computer, which will be interpreted by the UC&C application and the call will be muted.
Note: The call mute button may not function the same with some platforms, such as Webex and GoTo Meeting. For example, if the user mutes the microphone through the Webex software, the HDL200 may not indicate the call is muted on the LCD screen.
Volume up and volume down
When using the remote control, increasing or decreasing the volume will reflect the changes on the master volume control for the computer. This will work the same on all the applications that are loaded.
Recalibration by remote control
It’s possible to initiate a system recalibration through the remote control. The sequence is:
Press F4 five times in quick succession.
Press the Mute button on the remote control.
The HDL200 will enter recalibration mode. The LCD screen will display the calibration progress.
Remote control codes
The HDL200 remote control uses the NEC infrared transmission protocol, which specifies a carrier frequency of 38 kHz. If an infrared (IR) blaster (transmitter) is used to control the system, then the following codes can be programmed.
Function | Code |
---|---|
Call answer | 48 77 0A F5 |
Call hang-up | 48 77 0C F3 |
Mute | 48 77 1F E0 |
Volume (-) | 48 77 1C E3 |
Volume (+) | 48 77 07 F8 |
F1 | 48 77 05 FA |
F2 | 48 77 0F F0 |
F3 | 48 77 0B F4 |
F4 | 48 77 06 F9 |
Troubleshooting
If the remote control is not operating correctly, try the following:
Point the remote at the center of the LCD screen, at a 90-degree angle.
Move closer to the HDL200 (the optimum range is within 20 feet).
Confirm that the front of the remote is not obstructed.
Confirm that the path between the remote control and the HDL200 is not blocked.
Replace the batteries.
