VX-160EV/180EV Final FET upgrade modification
Please apply
fault FET with
following a temporally upgrade modification when you will have servicing to replace
VX-160EV/180EV
for production lot between #25 and #44. After #45 all modification
applied to production.
<NOTE>
DON NOT make transmit VX-160EV/180EV without antenna or dummy load connection.
We would like to recommend that it should be better replacing FET, if you will have to
apply this upgrade to current customer using VX-160EV/180EV radio.
1) Remove thermal sheet (RA0533600) form chassis
2) Put Silicon grease as follows
Put silicon grease at centre of here.
1.5mm
1.5mm
3) Put heat sink plate
Please make sure radio production lot number as following two heat sink plates.
Production lot # 45 and after should be applied RA0727570.
For # 25 to # 44: Please use heat sink plate as (RA0730600)
Put heat sink plate as (RA0730600)
