IMPORTANT NOTES BEFORE USE
✓
Before installing the station at the measurement site, make sure that the protective
caps on the four anti-bird spikes of the SA 277 outdoor microphone kit are removed. It
is recommended to use the protective caps during transportation, storage and other
operations with the instrument like, laboratory calibration, etc. to avoid personal injury.
✓
Only SVAN 977 and the controller can be disconnected and removed from the station
case by the user. All other disassembling work should be performed strictly by an
authorized service team.
✓
The producer does not recommend removing the controller without a sound reason.
Double check that the controller has a good fixation in the connector after
reconnecting.
✓
Do not remove the battery from the case! This operation must be done only by the
authorised service.
✓
SVAN 977
is powered from the external source and doesn’t use its internal batteries.
Internal instrument’s batteries must be removed for correct system operation and
safety reasons.
✓
The correct connection of the accelerometer or microphone is not signalled by the
controller therefore it is recommended to perform a test measurement each time the
station is turned on.
✓
During station operation it is recommended to charge the internal and external
batteries as often as possible; this will extend battery life. It is necessary to charge the
battery after any total discharge.
✓
Monitoring station and/or SB 272 should not be stored for a long time with discharged
batteries. Storing with batteries in discharged condition may damage them.
✓
If Monitoring station and/or SB 272 are planned to be stored for a long period of time, it
is recommended to charge their batteries to 100% capacity. Batteries should be
charged at least once per 6 months.
✓
If the storage period is longer than one year, a discharge/charge cycle must be
performed. To do this, leave the device turned on until the battery is completely
discharged. Then charge the battery to 100% capacity.
✓
Monitoring station and SB 272 have their own chargers, which are incompatible: SB
270 is a waterproof power supply for SV 277 PRO, whereas SB 273 is an indoor
charger for SB 272.
✓
The windscreen influences the free-field characteristics of the SA 277 outdoor
microphone kit; therefore, it is important to check its condition regularly. In the case of
visible degradation of the foam surface it must be replaced by the new one.
✓
If you use desiccator (silica gel) inside the outdoor microphone protection, it should be
regenerated after some period of use, when it changes colour to light grey, by drying it
for 3 hours in a temperature of 150°C. Desiccator should be inspected at least every
two weeks, and more often when used in conditions of high air humidity.
