Effective Range

WARNING: Using batteries
1. The PMR units operate with 4 1.5V AAA/LR03 regular Alkaline
or Ni-MH (nickel metal hydride) batteries.
2. Batteries and rechargeable battery pack should not be thrown
with domestic rubbish.You may hand them in at your nearest
collection point.
3. Do not leave batteries installed over a long period of time as
leakage may occur and this can destroy the radio.

SOLUTION
=Check the battery pack is installed properly.
=The batteries may be weak.
=Replace the old battery pack with a new one.
=Press the (UP) button to increase the
receiver volume level.
=The receiving signal may be weak and/or out
of range.
=If this happens press the M(Monitor) button.
=Key lock mode must be deactivated if the Key
lock icon is displayed on the LCD Screen.
=To change CTCSS sub-channels,press the MENU
button twice,the CTCSS icon blinks on the LCD
Screen.
=Press the (UP) or (DOWN) buttons to
change the CTCSS sub-channels.
=Batteries may be weak.
=Batteries may be weak.
=Replace with new batteries if the charge level
indicator gets low.
=Check the TX Power H/L setting. See the
"Effective Range" diagram.
=The maximum range will vary depending on
terrain and environment.
=Open fields provide the maximum range,while
steel/concrete structures, heavy foliage,and
use in buildings and in vehicles may limit the
range significantly.
=Wearing the radio close to the body,such as
in a pocket or on a belt,will decrease range;
change the location of the radio.
=If you are transmitting,speak in a normal tone
of voice, 5 cm away from the Mic
(microphone).
=If you are receiving, lower the volume to a
comfortable level.
=Radios too close. Radios must be at least 2
meters apart; increase your distance.
=Radios too far apart.Obstacles interfere with
transmission. Talk range is up to 8Km (High
power),3 Km (Low power) in clear unobstructed
conditions.
=Check the Scrambler mode setting.Both the
Transmitting and Receiving PMR units should
have the same Scrambler mode setting.
=Check the CTCSS code setting. Both the
Transmitting and Receiving PMR units should
have the same CTCSS code setting.
=Adjust the Mosquito Repeller Frequency and
check the most effective frequency to get the
best performance.
