Installation and operation

Inserting the batteries into the transmitter.

Open the battery cover by pushing the open mark and

sliding the cover down. Insert two 1.5V AA type dry cell

batteries or two 1.2V AA size NiMH rechargeable batteries

into the battery box. Match the battery terminals marked

“+” with the “+” on the label in the battery box.

Charging the batteries.

Use either charger AS402C, AS412C, AS436C or AS450C to

recharge. Simply place the receiver into the charger slot.

The recharging bottom contacts will connect to the charger

for fast charging. Usually full-charged batteries can be

used for approximately 10 hours.

Warning:

Do not place the receiver with Alkaline (type dry cell)

batteries into the charger.

AS201R Receiver operation.

1. The receiver has one switch only for power and

volume adjustment. Turn the switch clockwise to

active the receiver and adjust volume. Turn counter-

clockwise to deactivate the receiver and minimize

volume. When turning on the receiver, the PL light

will flash one time red, this indicates that the receiver

is functioning normally.

2. After switching on the power, the RX light turns

green, this indicates that the RF signal is received

normally.

3. The RX light turns red if the batteries are low and

need to be recharged or replaced soon. The reception

still can function for approximately 30 minutes. If the

batteries run out the RX light turns off and the PL

light turns red, this indicates that the receiver stops

functioning and the batteries need to be recharged or

replaced.

4. Use the channel selector with 16 pre-programmed

frequencies (0 to 9 and A to F) to select the channel

to transmit.

5. Use an earphone with 3.5mm input jack. When the

earphone is not connected the build-in speaker is

activated and sound can be heard directly from the

receiver.

6. Use Aux out when the receiver will be used for

amplification applications.

Maintenance

Avoid excessive heat

Don’t leave the receiver in the hot sun, on a radiator or

near other sources of high temperature.

Avoid rough handling

The receiver may be damaged if dropped.

Fully charged batteries

Before storing, fully recharge the batteries.

If possible recharge batteries once a month during storage

and again before first use.

Remove batteries

Remove the batteries when storing the unit for 3 months

or longer.

Battery terminals

Keep the contacts clean and inspect them often to ensure

that they are not corroded. If they become corroded,

polish them with a pencil eraser.

Trouble shooting

Problem

Solution

No power

Check if the power switch is

turned on.

Turn off the unit and check if the

batteries run out or are not

installed properly

No sound

Check if the transmitter and the

receiver use the same channel.

Check if the volume of the

transmitter or receiver is too low.

Check if the distance between

transmitter and receiver is too far.

Check if the transmitter and the

receiver are too close to metal

objects.

Sound interference

If there are two or more

transmitters in use, select

different channels for each

transmitter.

Check if there are other

transmitters near by and change

to a different channel.

Aux distortion

Check if the volume level of the

transmitter is too high or too low.

Feature

1. AS201R receiver, with build-in speaker, works with an

earphone. Aux out can be connected with an amplifier

for amplification applications.

2. AS201R receiver can use a DC+5V switching adapter

to provide power and can use chargers (AS402C,

AS412C, AS436C or AS450C) for recharging internal

batteries.
