· Connect the⑩POWER FEEDING LINE (RED) to the (+) side of transceiver Power Source with accessory ⑮POWER FEED.
CONNECTOR (DC12V±2V) (Fig. 3)
※If the transceiver microphone terminal has a output of DC Power feeding, DC5V〜9V 50mA, “D” Series microphone
conversion cable, optionally available, can be connected directly with getting the DC Power from transceiver microphone
terminal. The wiring of Power Feeding Line (RED)⑩is not required.
★⑮HOW TO CONNECT POWER FEEDING CONNECTOR★（Fig. 3）
1. Put the (+) side power cord of transceiver and Microphone
Power Feeding Line (Red) on grooves in the connector.
2. Fix them tentatively.
3. Press the insulation cover down to be locked with pliers.

★HOW TO USE★
· Press the ②TX BUTTON and the ⑦CONTROL BOX sounds out “pip” and TX INDICATOR lights up for indicating the
transmitting condition.
· Press the ③RX BUTTON and the ⑦CONTROL BOX sounds out “peep” ⑨TX INDICATOR(LED) lights off. The condition is
returned to RX (Receiving) mode.
· The Output Level is factory-preset to optimum level. But, the modulation level is too deep or shallow, the level can be
adjusted to appropriate level under following procedure.
Rotate the ⑧OUTPUTADJUSTMENT VOLUME to “Clockwise” for increase of output volume. Rotate it to “Anti-Clockwise”
to decrease volume. Under monitoring by Local Station, rotate it with “minus” driver carefully in the rotation range indicated
at (Fig.4). It turns 90°only for both left and right. Excessive turnmay damagethe ⑧OUTPUT ADJUSTMENT VOLUME.
Please be careful.
★NON-MODULATION PREVENTION CIRCUIT★
In case you set the condition to Transmitting mode without any intention, the
condition of non-modulation will continue and it may cause trouble to other
stations. To prevent such a condition, the alarm circuit built-in will activate
after 2.5 minutes continuous transmitting. The alarm sounds for 30 seconds
and the condition will be reset to receiving mode automatically.
If you want to continue Transmitting just after alarm sound, press the ③RX
BUTTON for stopping Transmitting Mode, then, press the ②TX BUTTON to
change to the transmitting mode.
※CAUTION
After pressing the ②TX BUTTON、the microphone may turn to transmitting or
receiving condition with “pip” or “peep” sound without control of microphone.
This condition is caused by imperfect positional adjustment between ⑥TX
BATTRY CASE and ⑦CONTROL BOX.
In this case, Non-Modulation Prevention circuit activates and after 2 or 3
minutes of continuous transmitting condition, the condition will return to
receiving mode automatically. However, Alarm circuit does not activate and
no alarm sounds from the unit It looks as the transmitting condition is
interrupted on the way of transmitting. Please be careful to this phenomenon.
In such a case, change the mounting position of ⑦CONTROL BOX.
★HOW TO REPLACE THE COIN TYPE LIGTHIUM BATTERY★
When you cannot control TX/RX from ④TX/RX CONTROL PART, ⑭Coin Type Lithium Battery is dead. Replace the battery to
new one as following order.
（A）Take ⑭Coin type Lithium Battery from ⑥Battery Case(TX) withtoothpick or stick. ( Push it out from ④TX/RX CONTROL
PART.) (Fig. 6b).
（B）Press the new ⑭Coin Type Lithium Battery (CR2032) into the ⑥Battery Case(TX) while keeping the (+) pole of battery
upper side. (Fig. 6a)
★RF FEEDBACK NOISE★
When transmitting with low power, the noise may be negligible. But when transmitting high-power, there are possibilities to
have abnormal modulation interference with offensive soundand other noise. In such a case, the bad matching between antenna
and coaxial cable may cause the problems., i.e., the Standing Wave effects onto microphone cable. To get the better condition,
please do not place the microphone cable in parallel to the antenna coaxial cable. Also please check the SWR between
antenna and transceiver.
