Cautions
 zWhen “ERROR” is displayed during the copy (clone) operation, check the connection of the clone 
cable and start the clone operation all again.
 zWhen the operation is terminated before completion due to loss of power during the copy (clone) 
operation, the FTM-400XDR/DE where the data is being copied to will automatically be reset. 
Check if there is any abnormality in the power supply and start the cloning operation over again

Tips
•  Make sure to turn the power to the radio OFF before connecting.
•  Refer to the operating manual of the TNC used on how to connect the TNC to a personal computer.
•  RF receive interference may occur because of noise occurring in the personal computer.
When signals cannot be received normally, keep the personal computer at a distance away from the 
radio and use a photo-coupler and noise filter to connect.

Caution
When transmitting a large volume of data, the transmission time gets longer and the radio will get 
heated up. When transmission continues for a long period of time, the overheating prevention circuit 
will act to lower the transmit power output. When transmission is continued further, transmission will 
be suspended automatically and the radio will go into the receive mode in order to prevent failure due 
to overheating.
When the overheating prevention circuit is activated and the radio goes into the receive mode, either 
switch turn OFF the power, or wait until the temperature drops in the reception mode.

 ●Externalspeaker
An optional high output and high sound quality waterproof external speaker “MLS-
200-M10” can be connected.
Plug the external speaker into the [EXT SP] jack at the back of the main body.
Tip
When an external speaker is connected to the [EXT SP] jack, there will be no sound from the internal 
speaker.
If you connect an External Speaker other than the MLS-200-M10 to the [EXT SP] Jack, 
use a Stereo Speaker only (Do not connect a Monaural Speaker plug directly into the 
[EXT SP] Jack.)
If you wish to connect a Monaural Speaker to 
the [EXT SP] Jack, use the supplied "Stereo to 
Monaural Plug" (see figure).
