VII. Getting Started
Charging the NiMH Battery Pack
You will need to charge the battery pack fully before
initial use. For best results from your charging cycle,
follow these tips:
• Ensure the ambient temperature is between 41 and
104° F (5 and 40° C) while charging. Temperatures
outside this range may not fully charge the battery.
• Always switch OFF the transceiver equipped with
a NiMH battery pack before charging. Using the
radio during the charging cycle will hinder correct
charging.
• Do not recharge the battery pack if it is already
fully charged. Doing so may cause the life of the
battery pack to shorten or the battery pack may
be damaged.
• If the battery is stored for 2 months or more, it is a
good idea to complete the charge / discharge cycle
two or three times to allow the battery capacity
to return to normal.
• Never dispose of the battery in fire - it can explode
causing personal injury.
• Never attempt to disassemble the battery or remove
its case material or charging contacts. Do not short
the battery terminals.
VII. Getting Started, continued
Charging the NiMH Battery Pack, continued
NOTE: The first few uses from the battery will not
be at normal capacity. After repeating the charge /
discharge cycle two or three times, the battery
capacity will increase to provide full capacity.
1. Plug the AC adapter cable in the adapter jack
located on the rear of the charger, then into
an AC outlet.
2. Slide the NiMH battery pack (or the radio
equipped with a NiMH battery pack) into the
charging slot.
3. Ensure that the metal contacts on the battery pack
come in contact with the charging terminals.
4. When charging the NiMH battery pack alone,
insert the provided plastic spacer (stored in
charger base) into the charging well, then insert
the battery pack.
5. The charger LED will light to advise that charging
has begun. Charge the standard battery pack for
9 hours. REMOVE THE PACK OR RADIO
FROM THE CHARGER.
IMPORTANT NOTE: The charger DOES NOT
TURN OFF AUTOMATICALLY after the charging
cycle has been completed. Damage to the battery
or reduced battery life may result if charged in
excess of the recommended charging time.
11
12
VII. Getting Started, continued
Attaching and Removing the Battery Pack
NOTE: After recharging the battery pack, REMOVE IT
FROM THE CHARGER.
The battery pack life is over when its operating time
decreases even though it is fully and correctly
charged. Replace the pack with the manufacturers
recommended model (TruTalk / Legacy ACC-203,
750 mAh or TruTalk / Legacy ACC-204, 1350 mAh).
Average battery pack life from the supplied 750 mAh
battery is 11+ hours; the optional 1350 mAh battery,
19+ hours. This service time is calculated using 90%
standby, 5% transmit and 5% receive time.
After charging the battery pack as described, you are
ready to install it to the radio body. Simply;
1. Match the four grooves of the battery pack with
the guides on the back of the radio.
2. Slide the battery pack up along the back of the
radio until the release latch locks.
To remove the battery pack, push down on the release
latch and slide the pack downward, and away from the
radio.
13
VII. Getting Started, continued
Installing the Antenna
Screw the antenna into the connector on the top of the
radio by holding the antenna at its base and turning
it clockwise until seated. Do not overtighten.
The antenna should never be used to carry your radio,
or as a base to clip radio accessories. Misuse of the
antenna can cause damage, and reduce your radios
performance.
Installing the Belt Clip
We recommend that the belt clip is installed on the
radio. It keeps the radio from coming in contact with
hot surfaces, and away from your body if heat build-up
occurs with excess transmissions.
Use the two supplied screws to install the belt clip. If
a replacement is needed, use a screw designed to the
exact specifications as the original, to prevent accidental contact with internal circuitry, or possible personal
injury. Never use glue in conjunction with the provided
screws. Some of the glues components may crack the
radio back panel, causing radio damage and possible
personal injury.
Installing the Speaker Microphone Jack Cover
If you are not using an accessory, install the provided
cover over the speaker microphone jack using the screw
supplied. This will keep the radio water resistant.
14
VII. Getting Started, continued
Attaching the Optional Speaker Microphone
1. Insert the speaker microphone jack into the radio.
2. Use the thumbscrew attachment on the speaker
microphone to make connection to the radio.
NOTE: The radio is not fully water resistant while the
speaker microphone is attached.
15
VIII. Radio Operation
Power On
Power on the radio by turning the power / volume
control clockwise out of detent. You will hear a
confirmation tone on power-up. To check radio
volume, press and hold the monitor button then
rotate the control to desired volume level.
The MURS-25 has two primary modes of operation:
1) Normal transmit and receive - This two-way radio
mode allows you to transmit and receive messages
with any other radio tuned to the same MURS
frequency as your radio.
2) Weather receive mode - This mode allows you to
listen to NOAA (National Oceanic and Atmospheric
Administration) weather broadcasts from the National
Weather Service. Refer to the "Weather (WX) Mode"
information in this manual for more information.
16
VIII. Radio Operation, continued
Normal Transmit and Receive
The MURS-25 is pre-programmed with the five (5)
Multi User Radio Service frequencies.
Select the channel that you wish to operate on, making
sure that all other radios you wish to communicate with
are on the same channel and CTCSS or DCS tone setting.
Refer to "Channel Frequency Selection" and "CTCSS /
DCS Tone Signaling" information in this manual for
more information.
Press the monitor button to check the channel for
activity. To avoid interrupting another use, make sure
the channel is clear before you begin transmitting.
To transmit, place the radio microphone approximately
2 (5 cm) from your mouth. Press and hold the P-T-T
bar while speaking in a normal tone. Release the P-T-T
bar when you are finished speaking; the radio will be
placed into receive mode.
When the battery pack voltage becomes too low for
operation to continue, the LED will blink red and a
tone will sound. The radio will allow only one more
transmission - change or charge your battery. Refer to
the "Low Battery Warning" section of this manual.
IX. Channel Frequency Selection

X. CTCSS / DCS Tone Signaling
CTCSS and DCS Tones prevent the radio from hearing
signals unless they match coded tones in your radio.
When a received signal has a code that matches your
code, squelch will open and you will hear the signal.
When a received signal has a code different from the
one set up in your radio, squelch will not open and
you will not hear the signal.
When you transmit on a channel set up with CTCSS
or DCS, the receiving radio must have a matching
code in order to hear your signal.
CTCSS Tones are selected from 38 standard and 11
