1. Use suitable screwdrivers that fit comfortably in the

driver slot. We recommend the screwdrivers below.

* Recommended screwdriver for manual adjustment

>VESSEL MFG.: NO.9000+1.7x30

(Murata P/N: KMDR080)

* Recommended screwdriver for automatic adjustment

>TORAY MFG.: JB-2225 (Murata P/N: KMBT070)

2. Don't apply more than 4.9N (Ref.; 500gf) of twist

and stress after mounting onto PCB to prevent

contact intermittence. If excessive force is

applied, the trimmer potentiometer may not

function.

3. Please use within the effective rotational angle.

Do not have a mechanical stop for over rotation.

In cases out of effective rotational angle,

the trimmer potentiometer may not function.

4. When using a lock paint to fix the slot position or

cover the rotor, please evaluate performance with

your product. Lock paint may cause corrosion or

electrical contact problems.
