10-5 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. To prevent such a condition from occurring,
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 time data display area 1.
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 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, in order
to give the unit time to detect moisture condensation.
10-6 Regular Checks
10-6-1 Digital Hours Meter
The digital hours meter can display seven items of
information, in corresponding display modes, about the
operational history of the unit. Use it as a guide in
scheduling periodic maintenance.
Display modes of the hours meter
H01: OPERATION mode
Displays the total number of hours the unit has been
powered on in units of 1 hour.
H02: DRUM RUNNING mode
Displays the total number of hours the drum has run with
tape threaded in units of 1 hour.
H03: TAPE RUNNING mode
Displays the total number of hours the unit has been in fast
forward, rewind, playback, search, recording or editing
(except for stop and still) mode in units of 1 hour.
H04: THREADING mode
Displays the total number of times tape has been threaded
in the unit.
H12: DRUM RUNNING mode (resettable)
Same as H02 except that the count is resettable.
This can be used as a guide in determining when to replace
the drum.
H13: TAPE RUNNING mode (resettable)
Same as H03 except that the count is resettable.
This can be used as a guide in determining when to replace
such components as fixed heads and pinch rollers.
H14: THREADING mode (resettable)
Same as H04 except that the count is resettable.
This can be used as a guide in determining when to replace,
for example, the threading motor.
