8) Perform the "Attaching the water-resistant sheet and
black sheet" on page 27.
■ Leakage Location Identifi cation
If step 6 of "Water Resistance Confi rmation" on page 25
fails, perform this procedure.
1) Prepare for a container that can contain the transceiver
suffi ciently and put water to a height of approximately 20
cm (7.87 inch) from the bottom of the container. The wa-
ter temperature must be between 10ºC (50ºF) and 30ºC
(86ºF).
2) Open the valve on the side of the pump, push the pump
piston and increase the inside pressure of the transceiver
to approximately 10kPa (right side of meter). If the meter
needle does not reach 10kPa when the piston is pushed
in to the end, perform the following steps.
a) Close the valve on the side of the pump.
b) Remove the pump from the hose.
c) Pull the piston of the removed pump to the end.
d) Insert the pump into the hose.
e) Open the valve and push the pump piston.
Repeat steps a) to e) until the meter needle indicates
approximately 10kPa (right side of meter).
Disassemble and reassembly the transceiver when
you do not reach approximately 10kPa even if the step
from a) to e) is repeated three times.
3) Wait for one minute after the meter needle reaches ap-
proximately 10kPa. Go to the next step if the meter nee-
dle indicates 5kPa or more. Disassemble and reassemble
the transceiver if the meter needle indicates 5kPa or
less.
4) Carefully place the transceiver into the water while the
inside of the transceiver is pressurized.

8) 进行第 27 页的"安装防水片和黑色薄片" 。
■泄漏位置确认
如果第 25 页的"防水性能确认"的步骤 6 失败，请执行此
操作。
1) 准备一个足以容纳手持对讲机的容器，将水放到距容器底
部约 20cm 的高度。水温必须介于 10ºC 和 30ºC 之间。
2) 打开泵侧的阀门，推动活塞，将手持对讲机的内部压力增
大到约 10k P a ( 仪表右侧 )。如果在活塞推到底时表针达不
到 10kPa，请执行以下步骤。
a) 关闭泵侧阀门。
b) 从软管中取出泵。
c) 将取出的泵的活塞拉到底。
d) 将泵插入软管。
e) 打开阀门并推泵的活塞。
重复步骤 a) 至 e)，直至表针指示约 10kPa( 仪表右侧 )。
如果步骤 a) 至 e) 重复三次后表针仍无法达到约 10kPa，
请拆卸并重新组装手持对讲机。
3) 表针达到约 10k P a 后，等待一分钟。如果表针指示 5k P a
或以上，继续执行下一步。如果表针指示 5kPa 或以下，请
拆卸并重新组装手持对讲机。
4) 在手持对讲机受压的状态下小心地将其放入水中。
