1. AC InPUt
It is a terminal to supply power to this device. The power used for this is PM-236 : Ac 120V or Ac 220-
240V, 50/60Hz, PM-248/260 : Ac 120-240V, 50/60Hz. do not bend by force, pull, twist, heat, or cut
the power cord. It may cause a fire or electric shock by damaging the cord.
2. IMPEDAnCE SElECtIOn SWItCh
It is a switch to select the impedance before connecting the speaker. select the impedance to use among 4Ω,
70V, 100V.
3. tEl In InPUt tERMInAl
It is a terminal to use by connecting with the telephone exchange. You can broadcast directly with the
※ When a signal is input to the Tel In input terminal, all other input signals will be lower as set by the Tel
transmitter of phone.
※ do not connect directly to the telephone network. (not connected to TnV-3 circuit)
In priority adjustment volume and the priority adjustment volume.
4. tEl In VOlUME COntROllER
It is a controller to control the volume of Tel In input. If you set the volume to minimum, a signal of 0dbV
(1Vrms) can be input sensitivity; if you set the volume to maximum, a signal of -20dbV (100mVrms) can be
input sensitivity.
5. tEl In PRIORIty COntROl VOlUME (tEl In MUtE)
This is a volume that adjusts the volume of InPuT 1~2, cHIMe, and sIren sound when a signal is input to
the Tel In. by using Tel In priority adjustment volume, user can adjust the input signal to InPuT 1~2,
cHIMe, and sIren. by using priority adjustment volume of InPuT 1~2, user can adjust the volume of InPuT
3~6, exT In.
