OPERATION
1) Open the battery cover, in accordance with the correct polarity into 2*1.5V battery.
2) Press power switch, power lamp lighting then going out, it means that the receiver
is on normal working. If the red lamp always lighting and corresponding LCD
display BAT under 2 segments, it means that the battery is low and advise the user
to change the battery at once.
3) The receiver include voice again adjusting device can follow each person’s sound.
4) AF output selecting switch. According the use of AF output signal to select the line
output (high impedance, low level output) or earphone output (100mw, 32Ω low
impedance output), to make sure that the signal can be at it’s best and without any
distortion.
5) Channel frequency set: To facilitate the large number of users using the system, at
the first channel’s frequency need reasonable set by group. The same place can’t
use same frequency. Channel frequency set follow below: press SET key first
display screen digital lashes, then press Key until get to right frequency, then
stop press 5 second, the receiver will auto-save & lock the result of setup.
6) 2.4V charging connector, it is to charge for 2*AA 1.2V battery. Both save money
and easy to moving use. The charging time depends on it’s capacity, it is advised
to use the charging battery with 1500mAh. And it’s charging time is 10-12 hours.
NOTES OF OPERATION
1) The battery working time is depend on earphone output volume be coming higher,
the current consumption will be more, the battery working time will be less. So
please select the earphone with high sensitivity, it is more better to over 110dB/MW.
2) If it is not used for long time. Please take out the batteries to avoid the battery
leachate to mar the inner circuit or accessories.

Safety Operation
Forbid
• Do not use charger outdoors or in moist environments, use only in dry
locations/conditions.
• Do not disassemble the charger, that may result in risk of electrical
shock or fire.
• Do not operate the charger if it has been broken or damaged in any
way.
• Do not place a portable radio in the area over an air bag or in the air
bag deployment area. The radio may be propelled with great force and
cause serious injury to occupants of the vehicle when the air bag
inflates.
To reduce risk
• Pull by the plug rather than the cord when disconnecting the charger.
• Unplug the charger from the AC outlet before attempting any
maintenance or cleaning.
• Contact Retekess for assistance regarding repairs and service.
Protect your hearing
• Use the lowest volume necessary to do your job.
• Turn up the volume only if you are in noisy surroundings.
• Turn down the volume before adding headset or earpiece.
Turn off your radio power in the following conditions:
• Turn off your radio before removing (installing) a battery or accessory
or when charging battery.
• Turn off your radio when you are in a potentially hazardous
environments: Near electrical blasting caps, in a blasting area, in
explosive atmospheres (inflammable gas, dust particles, metallic
powders, grain powders, etc.).
• Turn off your radio while taking on fuel or while parked at gasoline
service stations.
To avoid electromagnetic interference and/or compatibility conflicts
• Turn off your radio in any facility where posted notices instruct you to
do so, hospitals or health care facilities (Pacemakers, Hearing Aids
and Other Medical Devices) may be using equipment that is sensitive
to external RF energy.
• Turn off your radio when on board an aircraft. Any use of a radio must
be in accordance with applicable regulations per airline crew
instructions.
Avoid Burns
Antennas
• Do not use any portable radio that has a damaged antenna. If a
damaged antenna comes into contact with the skin when the radio is
in use, a minor burn can result.
Batteries (If appropriate)
• When the conductive material such as jewelry, keys or chains touch
exposed terminals of the batteries, may complete an electrical circuit
(short circuit the battery) and become hot to cause bodily injury such
as burns. Exercise care in handling any battery, particularly when
placing it inside a pocket, purse or other container with metal objects.
Long transmission (If appropriate)
• When the transceiver is used for long transmissions, the radiator and
chassis will become hot.
