TERA

Battery Information

Please use and charge only a TERA approved battery. Attempting to use a different
battery type may result in overheating or explosion of the battery, causing damage to
the radio and the potential for physical injury.

Notes:

1. Do not short-circuit the battery terminals or dispose the battery in fire. Never attempt to
disassemble the battery pack.

2. Charge the battery in 32-105

°F temperature. Otherwise the battery may not fully charge.

3. Turn off the radio before your initial charge. Use of the radio while charging may cause noise

or interfere during reception or transmission.

4. Do not pull/plug the adapter and the battery during charging, to avoid interference with the

charging procedure.

5. NEVER charge the battery or radio with battery if they are wet. Before charging, you should dry

them off with a towel or cloth to avoid danger.

9

Warning:

Conductive metals such as jewelry, keys or decorating lace may result in short circuit
and generate a large quantity of heat when coming in contact with battery electrodes.
Treat any battery carefully especially when placing it into pocket, wallet or other metal
container as it can short out.

Charge Operation

Please charge as follows:

1. Turn off the radio.

2. Plug the AC connector of adapter into an AC output socket

TERA

3. Vertically insert the battery or radio equipped with battery into the charger. Make sure the
charger and battery are well contacted.

4. After the radio and/or battery are inserted into the charger, the LED glows red and that means

the charger is ready for normal charging; if the LED flashes red, it means the remaining battery

power is too low and a trickle charge is in process. After the battery power has reached a
certain amount during trickle charge, the charger automatically turns to normal (fast) charge
mode (solid red colored LED).

5. The battery is fully charged (97%-100%) when LED glows green. The charger stops charging

automatically.

Caution when Charging the Battery

1. The battery is not fully charged from the factory. Please charge the battery before initial use or

after long-period of storage.

2. Repeat charging 2 to 3 times will make the battery reach its best capacity. Please replace or

charge the battery if battery power is low after repeated charges.

Note

Trickle charge is not allowed to exceed 30 minutes. If the LED is still flashing in red after 30

minutes, it means that the charger cannot provide power to the battery. Check if the battery or
charger is damaged.

TERA

Software Overview

The TERA programming software was developed to maximize all the functions of the TERA DMR
radio. Programming can be as simple as a few channels or developed to include all 64 Zones of
16 channels totaling 1,024 unique channels.

Channel Data Entry

TERA software was developed with Amateur users in mind. As an example when programming a
Zone of 16 channels for a repeater, enter the first channel data first. Then click “Add” for additional
channels up to 15. The main channel data will be duplicated. Then go back and change the
predefined Talkgroups and Slots, thereby saving a tremendous amount of programming time.

35

Example of the “Add” function in duplicating row data

Next enter the Talkgroup names for each of the 16 channels. Then go back to the first channel and
expand the row by clicking on >> to select a programmed Contact that matches the Channel Name,
that was previously entered. If the Contact was not previously defined go to the Contact/Talkgroups
section and enter the new Contact information. Then select the appropriated Slot.

TERA

Zone Organization

A key feature is the organization of Zones in the software. Zones can be moved up and down in any
order and added or deleted. A unique feature is that channels follow the Zones when the Zones are
moved, thereby allowing the channels to be inserted and not having to be in numerical order.

37

Contact Sheet Database Import

The latest Contact Database for the TERA DMR radio is located at www.tera.co/DMR This contact
database is formatted to directly import into the TERA DMR radio. No contact manager software is
needed. Talkgroup and Personal frequent IDs are located in the Talkgroup/Contact database and are
not merged into the Contact Sheet.

Download the Contact Sheet database to your desktop or a specific folder for importing. In the
following example the folder is named TERA DMR. The TERA software will look for the .csv file.

TERA

After selecting the file you will see the database starting to load.

39

Since the Amateur database is ever growing and large, it may take a minute for the database to
appear in the display window.

Safety

The TERA DMR handheld transceiver has been carefully designed to provide you with
years of safe, reliable operation. As with all electrical equipment, however, there are a
few basic precautions you should take to avoid hurting yourself or damaging the radio:

• Read the instructions in this handbook carefully. Be sure to save it for future reference.

• Read and follow all warning and instruction labels on the radio and owner’s manual.

• Do not carry the transceiver by the antenna. This may damage the antenna or antenna
terminal. Grasp the handheld by its base (not the antenna) when you need to place or
remove it.

• Do not keep the radio with the antenna very close to, or touching exposed parts of the
body, while transmitting. TERA radios will perform best, if you speak 2-4 inches away
from the microphone and the radio is vertical.

• Be sure the “PTT” key is not pressed when you do not need to transmit.

• Do not operate the radio near unshielded electrical blasting caps or in an explosive
atmosphere.

• Do not transmit without the antenna fitted on the radio. Though it is provided with a
protection, it may damage the TX output final stage.

TERA

• Respect the environment conditions. The radio is designed to be used in heavy
environments, however avoid exposing it to extremely hot or cold temperature (out of
the range between –20 to +140°F). Do not expose the transceiver to excessive
vibrations as well as dusty or rainy locations.

• Never try to disassemble or service the radio by yourself (aside from the routine
maintenance described in this handbook). It may cause damage to the radio transceiver
and void your warranty requiring extensive repair work. Always contact your local
dealer for assistance.

• Use only authorized accessories. Using non TERA radio brand accessories may
seriously damage your handheld transceiver and void your warranty.

• Do not spill liquid of any kind into your radio. If the transceiver gets wet, immediately
dry it by a soft and clean cloth.

• Switch the radio off before you clean it. Follow the directions described in the
paragraph “Care and maintenance”.

• Handle the battery properly. Never place the LI-ion battery in your pocket or purse with
loose coins. This could result in short circuiting the battery.

WARNING

Your wireless hand-held portable transceiver contains a low power transmitter. When
the Push-to-Talk (PTT) button is pressed it sends out radio frequency (RF) signals. The
device is authorized to operate at a duty factor not to exceed 50% TX and 50% RX.
In August 1996, the Federal Communications Commission (FCC) adopted RF exposure
guidelines with safety levels for hand-held wireless devices. To maintain compliance
with the FCC’s RF exposure guidelines, this transmitter and its antenna must maintain
a separation distance of least 2 inches from your face. Speak in a normal voice, with the
antenna pointed up and away from the face at the required separation distance. The belt
clip is for storage purposes only. AVOID TRANSMITING ON HIGH POWER WHILE RADIO
IS ATTACHED TO YOUR BELT. To transmit, hold the device away from your body and
ensure the antenna is at least 2 inches from your body when transmitting.
