Turning the power on
Connect 5.0V / 1A power adaptor to ⑧ DC adaptor input located on the side of WI-249LM.
Turn the ⑥
Display, a small dot LED is on to indicate the device is on.
•
•
Paring (Main / Sub devices)
The main device allocates a number to each sub device from number ‘00’ to ‘99’ when pairing. For
example, if you would like to allocate the number ‘03’ to a WI-249LS, use the ⑤
choose ‘03’ and press ⑦
When in pairing mode, two dot LEDs are blinking. When pairing is completed, ‘03’ disappears and a
double beep will sound. You can repeat the same method to pair all other sub devices with the main
device. Only the numbers between 00 and 99 are valid for allocation.

When Sub device (WI-249LS) Pages Main device (WI-249LM)
When a sub device (WI-249LS) pages the main device (WI-249LM), the seven-segment display on
the main device (WI-249LM) displays the ID number of the sub device (the number allocated to the
sub device from the pairing process). When paged, the display blinks repeatedly every 0.25
seconds.
•
•
When Main device (WI-249LM) Pages Sub device (WI-249LS)
Use the ⑤ Select button to choose a sub device you wish to page and press the ④ Paging button.
While paging, the display blinks repeatedly every 0.25 seconds. If the ④
without any sub device being selected, the sub device with the allocated number ‘00’ will be paged
(*** the main device WI-249LM can page any sub-devices only when the sub devices are
connected to DC power adaptor, not running on batteries).

After replacing the batteries, you need to page the main device to register the new battery level
value and the main device must answer the call to register the new value.
•
•
Replacing a Sub device (WI-249LS)
If any of the paired sub devices is replaced, please try to use the same ID number of the removed
device to minimize the ID allocating processes.
•
•
Inverting the FND Display on Main device (WI-249LM)

Forced Voice Forwarding Function (PTT Mode)
WI-249LM/S devices are half duplex type which automatically determines the direction of audio
communication for effective sound quality by eliminating hauling and echo effects. If one side
creates a constant loud noise or talks loud constantly, the microphone on the other side is
deactivated at all times providing one sided communication. In this case, initiate a talk while
pressing the “Select button”. By releasing the Select button, the device is back to normal talking
mode.
•
•
Repeater
This is an optional mode for a sub device, WI-249LS.
After registering main and sub devices to a repeate, the communication is now enabled only
through the repeater. It means if the repeater is turned off, the registered devices cannot
communicate each other.
•
•
Repeater Setting
Connect 5V / 1A DC power adaptor to WI-249LS. By pressing the ④ Select button and ③ Paging
10
button simultaneously for 5 seconds, you can turn the sub device into a repeater mode. The Red
LED blinks every 1 second to indicate a repeater mode. To turn the power off, use the ⑤
switch at the bottom of the device. Repeater mode is enabled only if a constant power is supplied
by a power adaptor (5V / 1A DC power adaptor).
•
•
Pairing (Main WI-249LM/Repeater)
Press the ⑥ Volume switch on a repeater for 5 seconds to go in to pairing mode. The Red LED
blinks every 0.5 seconds to indicate that the repeater is in pairing mode. A sound of a double beep
indicates the pairing is completed. The pairing mode lasts for 60 seconds.
