NX-200
■ Water Resistance Confi rmation
1) Install the universal connector cap over the universal
connector.
2) Remove the water-resistant sheet (G11-4331-04) and
black sheet (G11-4440-04) attached to the right side of
the rear of the chassis using a pair of tweezers q. This
water-resistant sheet allows air to pass, but not water.
Note:
Take suffi cient care to prevent damage to the surface of
the chassis when removing the water-resistant sheet.
3) There is a screw hole under the water-resistant sheet.
Insert the hose adapter into this screw hole while turning
it w.
4) Insert the water-resistant inspection jig hose into the
hose adapter e.
Note:
The piston of the water-resistant inspection jig pump
must be pushed in to the end.
5) Turn and open the valve on the side of the pump of the
water-resistant inspection jig, then pull the pump piston
to reduce the pressure in the transceiver. Pull the piston
until the meter needle of the water-resistant inspec-
tion jig indicates 10kPa (left side of meter). If the meter
needle does not reach 10kPa when the piston is pulled
to the end, perform the following steps.

5) 转动并打开防水检验夹具泵侧的阀门，然后拉泵的活塞以
减小手持对讲机内的压力。拉动活塞，直至防水检验夹具
的表针指示 10k P a ( 仪表左侧 )。如果在活塞拉到底时表针
达不到 10kPa，请执行以下步骤。
