Moisture Condensation; Regular Checks; Digital Hours Meter - Sony HDW-1800 Operation Manual

10-4 Moisture
Condensation
When the unit is suddenly moved from a cold to a warm
location, or used in a very humid place, moisture from the
air can condense on the head-drum. This is called moisture
condensation. If the tape is run in this state, it can adhere
to the drum and damage the tape. To prevent this, the unit
is provided with a moisture detecting function.
If moisture condenses on the head-drum while the unit is
in use, the ALARM indicator lights and "ERR-10" is
displayed in the time data display.
ER R- 10
ALARM indicator
"ERR-10" appears in the time data display.
If this happens, the drum and capstan motors stop and the
cassette is automatically ejected. Then, the drum starts to
rotate again to dry its surface. In this state, the unit is not
operable. When the moisture has evaporated, the error
message disappears and the ALARM indicator goes off.
If "ERR-10" appears and the ALARM
indicator lights immediately after powering
the unit on
Leave the unit powered on and wait until the error message
disappears and the ALARM indicator goes off.
While the indicator is lit, you cannot insert a cassette.
When the indicator goes off and the error message
disappears, you can use the unit.
If you move the unit from a cold to a warm
location
Leave the unit powered off for about 10 minutes, since it
takes some time to detect moisture condensation in this
state.
