Chapter 1. - Initial Setup
Safety Information
The following safety precautions should always be observed during operation, service, and
repair of this equipment.
• Qualified technicians shall service this equipment only.
• Do not modify the radio for any reason.
• Use only BTECH supplied or approved batteries and chargers.
• Do not use any portable radio that has a damaged antenna. If a damaged antenna
comes into contact with your skin, a minor burn can result.
• Turn off your radio prior to entering any area with explosive and flammable materials.
• Do not charge your battery in a location with explosive and flammable materials.
• To avoid electromagnetic interference and/or compatibility conflicts, turn off your radio
in any area where posted notices instruct you to do so.
• Turn off your radio before boarding an aircraft; any use of a radio must be in accordance
with airline regulations or crew instructions.
• Turn off your radio before entering a blasting area.
• For vehicles with an air bag, do not place a radio in the area over an air bag or in the air
bag deployment area.

• Do not expose the radio to direct sunlight over a long period of time, nor place it close
to heating source.
• When transmitting with a portable radio, hold the radio in a vertical position with the
microphone 3 to 4 centimeters away from your lips. Keep antenna at least 2.5
centimeters away from your body when transmitting.
If you wear the radio on your body, ensure the radio and its antenna are at least 2.5
centimeters away from your body when transmitting.
Exposure To Radio Frequency Energy
Your BTECH radio is designed to comply with the following national and international standards and guidelines
regarding exposure of human being to radio frequency electromagnetic energy:
- United States Federal Communications Commission, Code of Federal Regulations: 47 CFR part 95 sub-part E
- American National Standards Institute (ANSI)/Institute of Electrical & Electronic Engineers (IEEE) C95. 1-1992
- Institute of Electrical and Electronic Engineer (IEEE) C95. 1-1999 Edition
- National Council on Radiation Protection and Measurements (NCRP) of the
United States, Report 86, 1986
- International Commission on Nonionizing Radiation Protection (ICNIRP) 1998
To control your exposure and ensure compliance with the general population or uncontrolled environment exposure
limits, transmit no more than 50% of the time. The radio generates measurable RF energy exposure only when
transmitting.

Assembly
Before the radio is ready for use, we need to attach the antenna and battery pack, as well as
charge the battery.
Antenna
This transceiver is fitted with a Male SMA connector. To mount
your antenna (Female SMA connector), align the two connectors
and turn clockwise until it stops.
• Do not over-tighten your antenna to avoid damage to the connectors.
• When installing the antenna, don't grip it by the top. Grip by the base and turn.
• If you use an external antenna, make sure the SWR is about 1.5:1 or lower to avoid
damage to the transceiver. Use a SWR Meter or bridge which is rated for use in the UHF
GMRS Band (460-470 MHz)
• Do not hold the antenna with your hand while transmitting.
• Never transmit without an antenna. You will damage the transmitter requiring repair.

Belt clip
At the back of the radio there are two parallel screws mounted
above the battery, remove these and thread them through the
holes on the belt clip as you screw them back into the radio body.
Do not use any form of glue to fix the screws on the battery
clip. The solvents in the glue may cause damage to the
battery casing.
Battery
Before attaching or removing the battery make sure your radio is turned off by turning the
power/volume knob all the way counter-clockwise.
Installation
Make sure the battery is aligned in parallel with the radio
body with the lower edge of the battery about 1-2cm below
the edge of the radio.

Once aligned with the guide-rails, slide the battery upward until you hear a click as the battery
locks in place.
Removal
To remove the battery, press and hold the battery releases on the sides of the battery pack as
you slide the battery downward. You may need to push the top of the battery to start removal.

Charging and Battery Maintenance
Charging
Battery should be fully charged before initial use. Optimum battery efficiency will be
achieved after the three full battery charge and discharge cycles.
Follow these steps to hook up and use the charger:
1. Plug the DC connector of the power adaptor into the charger base.
2. Plug the AC connector of the power adaptor into a main AC wall outlet.
3. Place the radio in the charging slot on the charger.
4. For best charging practices, have the radio off while charging.
5. Make sure the radio is making contact with the charger. When the red LED comes on
steady, your radio is charging.
6. The radio is fully charged once the charger's green status LED glows steady. Please
remove the radio at that time to avoid over-charging your battery.

The charger and battery are fitted with matching notches so that you can charge your
battery on its own! This is practical if you have two batteries. That way you can charge
one battery while still using your radio.
Radio should be turned OFF during charge cycle
Battery Maintenance
The battery for your radio comes uncharged from the factory; please let it charge for at least
four to five hours before you start using your radio.
• Use only batteries approved by the original manufacturer.
• Never attempt to disassemble your battery pack.
• Do not expose your batteries to fire or intense heat
• Do not leave battery or radio in direct sunlight for prolonged time
• Dispose of batteries in accordance with local recycling regulations. Batteries do not
belong in your trashcan!

Prolonging the life of your battery
• Only charge batteries in normal room temperatures.
• When charging a battery attached to the radio, turn the radio off for a faster charge.
• Do not unplug the power to the charger or remove the battery and/or radio before it's
finished charging.
• Never charge a wet battery.
• Batteries wear out over time. If you notice a considerably shorter operating time with
your radio, please consider purchasing a new battery.
• Battery performance will be reduced in temperatures below freezing. When working in
cold environments, keep a spare battery on you. Preferably inside your jacket or in a
similar location to keep the battery warm.
• Dust can interfere with the contacts on the battery. If necessary, wipe the contacts with a
clean cloth to ensure proper contact with radio and charger.
If your battery has become wet, remove it from the radio, wipe it dry with a towel and
put it in a plastic bag with a handful of dry rice. Tie the bag up and let it sit overnight.
The rice will absorb any remaining moisture in the battery.
This method is only effective against minor splashes (light rain for instance). A soaked
radio may very well be beyond repair.

Storage
Partially charge your battery before long-term storage to prevent damage from over- discharge.
While lead acid must always be kept at full charge during storage, this radio uses a lithium-based
battery and should be stored at around a 40 percent charge. This level minimizes age-related
capacity loss while keeping the battery in operating condition and allowing self-discharge.
To avoid severe capacity degradation of your battery while in long-term storage, please cycle
the battery at least every six (6) months.
Store your batteries in a cool and dry place, never above normal room temperatures.
