HOW TO REPLACE THE INTERNAL BATTERY
If a Cold Start occurs frequently (the transceiver cannot
start GPS positioning after the transceiver is turned ON)
even though the transceiver has been continuously used, the
internal battery may be degraded. When the internal battery
terminal is less than 1.4V after charging, use the following
procedure to replace the internal battery.
CAUTION: THE OPERATOR MUST WEAR AN ANTISTATIC
BAND WHEN REPLACING THE BUILT-IN BATTERY IN ORDER TO PREVENT STATIC DISCHARGE. THE INSTALLED
IC MAY BE DAMAGED BY A DISCHARGE OF STATIC
ELECTRICITY.
1. Remove the KMC-47GPS/48GPS from the transceiver
and 4 screws on the rear panel.
3. Remove the GPS unit installed in the upper part of the microphone.
CAUTION: DO NOT DAMAGE CABLES WHEN REMOVING THE GPS UNIT.

4. Remove the internal battery in the GPS unit by using the
soldering iron. Replace the battery with a new battery.
CAUTION: BE SURE THE POLARITY OF THE BATTERY
BEFORE INSTALLING IT.

CIRCUIT DESCRIPTION
RESETTING THE GPS UNIT
The location data is calculated by the GPS unit and is
then sent to the transceiver via the RXD terminal of the connector (universal or 2-pin).
When the transceiver is turned OFF, the GPS unit enters
to backup mode and the power is supplied by the internal
rechargeable lithium battery.
When the transceiver is turned ON, the GPS unit enters
to normal operation mode and the power is supplied from
the transceiver via the 5M terminal of the connector (universal
or 2-pin). While the transceiver is turned ON, the internal rechargeable lithium battery charges.
It takes approximately 40 seconds to calculate the location
data when the GPS unit is “cold started” (full initialization).
When the KMC-47GPS/48GPS cannot determine the
position in a situation where GPS data is received, use the
following procedure to reset the GPS unit.
Reset the GPS unit by removing the internal battery and
then re-installing it. (To remove the internal battery, refer to
“HOW TO REPLACE THE INTERNAL BATTERY”.)
GPS OPERATION CHECK METHOD AFTER REPAIRS
Check the GPS operation according to the following procedures.
1. Prepare the transceiver which incorporate the GPS function. (Set the GPS Position Display to a key, such as the
[S] key, with the FPU beforehand.)
2. Connect the KMC-47GPS/48GPS to the connector (universal or 2-pin) on the transceiver.
3. Turn the transceiver power ON.
4. Go outside, then press the [S] key (the key that you previously set as the GPS Position Display) on the transceiver.
5. The “GPS” and latitude information are displayed on the
LCD of a transceiver.
Note:
・The KMC-47GPS/48GPS has an internal battery to backup the built-in pinpointing data. When the internal battery is
charged, the transceiver will retain the pinpointing data (the
last positional information) for approximately 20 days. (When
used for the first time, it takes approximately 10 hours to fully
charge the internal battery.)
・When the internal battery is in the discharged state, pinpointing data returns to its initial value. When the positional
information is at its initial value while turning on the transceiver, the life cycle of the internal battery is considered.
