Safety Information
IMPORTANT –READ ALL INSTRUCTIONS carefully
and completely before operating your radio and
retain this manual for future reference. Failure to
observe the instructions could result in personal
injury, death, and/or damage to your radio,
accessories and/or other property.
Batteries & Chargers
This equipment contains a lithium-ion battery pack.
NEVER dispose of the lithium-ion battery in fire. An explosion may
result.
DO NOT short-circuit the battery pack.
DO NOT charge the lithium-ion battery in any other charger.
DO NOT operate the charger if it has been broken or damaged in
any way.
DO NOT disassemble the charger. It is not a user serviceable item.
ALWAYS dispose of lithium-ion batteries according to local
regulations.
ALWAYS switch the radio OFF when charging battery.
ONLY use approved accessories.
ONLY use the charger in dry locations. The charger is not suitable
for outdoor use.
Radio Antenna
DO NOT use any portable radio that has a damaged antenna. If a
damaged antenna comes into contact with the skin, a minor burn
may result.
DO NOT change or modify the antenna. Unauthorized antennas,
modifications, or attachments could damage the radio and violate
its compliance status.
DO NOT hold the antenna when the radio is in use. Holding the
antenna reduces talk range and may cause bodily harm.

5
Use In Vehicles
You must comply with local, regional and national laws and
regulations regarding the use of two way radio in vehicles at all
times.
DO NOT place your radio in the area adjacent to or in front of an
air bag or in the air bag deployment area.
Air bags inflate with great force. If a radio is placed in the air bag
deployment area and the air bag inflates, the radio may be
propelled with great force and cause serious injury to the
occupants of the vehicle.
Potentially Explosive Atmospheres
This radio is NOT Intrinsically Safe. Turn your radio OFF prior to
entering any area with a potentially explosive atmosphere.
Sparks in such areas could cause an explosion or fire resulting in
injury or even death.
Note: The areas with potentially explosive atmospheres are often,
but not always, marked. They will include fuelling areas such as
below decks on shops, fuel or chemical transfer or storage facilities,
areas where the air contains chemicals or particles, such as grain,
dust or metal powders, and any other area where you would
normally be advised to turn off your vehicle engine.
Blasting Caps and Hazardous Areas
To avoid possible interference with blasting operations, switch off
your radio when you are near electrical blasting caps or in a
“blasting area” or other area signposted: “Switch off two-way
radios”or similar. Obey all signs and instructions.
Radio Operation and EME Exposure
NEVER operate your radio with the antenna less than 5 cm from
your body and keep transmitting time minimal.
ALWAYS use the supplied belt clip if you wear a radio on your
body when transmitting.

6
Electromagnetic Interference
Nearly every electronic device is susceptible to electromagnetic
interference (EMI). To avoid the possibility of electromagnetic
interference and/or compatibility conflicts, switch off your radio in
any location where posted notices instruct you to do so, such as
health care facilities.
Use In Aircraft
When instructed to do so, switch OFFyour radio on board an
aircraft.
Any use of a radio must be in accordance with applicable
regulations and aircrew instructions.
Pacemakers
The Advanced Medical Technology Association recommends that
a minimum separation of 15 cm be maintained between a
handheld wireless radio and a pacemaker. These
recommendations are consistent with the independent research
by, and recommendations of, the U.S. Food and Drug
Administration.
Persons with pacemakers should:
Always keep the radio more than 15 cm from their pacemaker
when the radio is switched ON.
Do not carry the radio in the breast pocket.
Use the ear opposite the pacemaker to minimize the potential
for interference.
Turn the radio OFF immediately if there is any reason to
suspect that interference is taking place.
Hearing Aids
Some radios may interfere with hearing aids. In the event of such
interference, please consult your hearing aid manufacturer or
supplier to discuss alternatives.

7
Other Medical Devices
If you use any personal medical device, consult the manufacturer
of your device to determine that it is adequately shielded from RF
energy.
Your physician may be able to assist you in obtaining this
information.
User Safety
NEVER hold the radio so that the antenna is very close to, or
touching exposed parts of the body, especially the face or eyes,
while transmitting. The radio will perform best if the microphone is
held 5–10 cm from the lips and the radio is vertical.
NEVER operate the radio with a headset or other audio accessory
at a high volume level.
NEVER short the terminals of the battery pack.
NEVER use your radio outdoors during a thunderstorm.
DO NOT push the PTT button if you do not intend to transmit.
DO NOT modify the radio for any reason.
DO NOT use any non-approved battery packs or chargers.
AVOID storing or charging your radio in direct sunlight.
AVOID storing, using or charging your radio where temperatures
are below -20° C or above +60° C.
AVOID exposing the radio to heavy rain, and NEVER immerse it in
water. The radio construction is water resistant and NOT
waterproof (submersible).
DO keep the radio out of reach of babies and small children.
Changes or modifications to your radio that are not expressly
approved or authorised may void your authority to operate the
radio under relevant laws and regulations.

We hereby declare that the Opus T2 radio is compliant with the
essential requirements and other relevant provisions of Directive

Charging the battery pack
Your Opus T2 radio is supplied with a rechargeable lithium-ion
(Li-ion) battery pack.
This battery should be fully charged before first use to ensure
optimum capacity and performance.
The battery is designed specifically for use with the Opus T2 and

whilst attached to the radio.
The supplied lithium-ion (Li-ion) battery can be safely re-charged
after only partial use. It is not necessary to fully discharge the
battery between charges.
Operating time
To extend the operating time (endurance) of your radio between
charges, your radio is equipped with a Battery Save feature which
is enabled by default.
The operating time you experience will vary based on your own
usage pattern.
The standard Opus T2 battery is designed to deliver at least 18
hours operation with a usage pattern of 5% transmit, 5% receive
and 90% standby.
