1.  Turn the transceiver’s power off by pressing and holding in the 

 switch for 1/2 

second, then remove the FBA-28 Battery Case or SBR-32MH Ni-MH Battery Pack 

from the transceiver. Additionally, disconnect the DC cable from the INPUT: 13.8V  

jack on the rear panel of the transceiver, when operating the FT-818 with a DC power 

supply.

2.  Referring to Figure 1, remove the shoulder belt bracket and its two screws from both 

side of the transceiver, then remove the five screws affixing the top case of the trans-

ceiver, and remove the top case; disconnect the speaker’s connector when you remove 

the top case.

3.  Refer to Figure 2 for the mounting locations for the optional filters. Position the filter 

so that its connectors are aligned with the mounting pins on the board, and push it into 

place.

4.  Replace the top case (remember to replace the internal speaker’s plug), and connect 

the  FBA-28 Battery Case or SBR-32MH Ni-MH Battery Pack (and/or attach the 

DC power supply), and turn the transceiver on by pressing and holding in the 

 

switch.
