using BOTH THUMBS and slide top backwards a little until
the two front (top) locking tabs are free of front panel slots
- NOW

the two used cells using a fingertip pushing each cell at
positive end against minus terminal spring while lifting positive
end up and free of positive terminal
- Carefully
dispose of used cells. Check that inside of battery holder
and replacement cells are clean, free of dust/ lint, oils/grease
by wiping the battery terminals (ends) of the cells with a clean
cloth before installing.
- TIP:
Give each cell a spin rotation to securely seat the battery
and electrical contacts.

PA-24NJ
MODEL Specifications (Shared
by all models)
|
|
|
The
DSM + PA-24NJ is a system with extraordinary (extreme)
low frequency (bass) ability to < 1 cycle with LoCUT
OFF.
|
For example, recordings of acoustic instrument music, nature/urban
ambient, and general effects recordings most often benefit with
LoCUT OFF. |

|
|
Recording these extended low frequencies is very useful or a
liability depending on subject, the ambient (background),
and purpose (end use). |
LoCUT
ON is suggested for reducing low frequency noise (background
rumble from air conditioning/motor traffic) in recordings of
vocal narration, lecture, and interviews. |

USING PA-24NJ WITH PORTABLE RECORDERS |
 Plug
in PA-24NJ output plug secured to deck as shown in illustration at left |
 |
 |
|
AFTER
USING SYSTEM FOR A FEW TIMES:
Clean 3.5mm type mic plug BEFORE inserting into PA-24NJ with
supplied cleaning cloth, then rotate plug several times to secure good
noiseless connection.
A
single drop of pure +91% isopropyl alcohol ONLY on the metal part
of the mic and preamplifier output plug just BEFORE inserting into the jacks will insure a clean noiseless
connection
