Louder TalkBack Mod:
* Remove the radio covers and locate the Connection points shown in diagram A above.
* Solder a 1/4 Watt 4.7K ohm (4700) Resistor to the points in the diagram (See below for Alternate Values)
This Value may need to be adjusted for proper talkback level - (Lower resistor values = lower audio)
Try values between 1.8k through 4.7k to get the desired level of Talkback.
* Power On the Radio and test the increased TalkBack Level.
* If the level is too high or too low, adjust the resistor value accordingly.
Caution:
This radio uses SMT (Surface Mount Technology) and most of the components are tiny and delicate!
This type of work requires proper tools and skills that may be beyond the level of some repair shops.
Make sure that the shop making these mods is capable and has proper tools to complete this type of work
before proceeding. Mistakes and errors are usually costly! - We take No Responsibility and No Guaran-
tees!
