Do not store the battery inside vehicles in hot weather.
Do not short-circuit battery contacts.
Do not puncture or obstruct membrane vents.
Battery should be stored at room temperature charged to about 30-50%
capacity.
Charge battery once every 3 months to prevent overdischarge.
Battery must be charged only when its temperature has settled between 0°C
and 45°C.
Temperature range over which battery can be discharged is between -20°C
and 60°C. Use of the battery outside of the specified range reduces
performance and life expectancy.
When battery reaches end-of-life, insulate terminals with adhesive tape or
similar material before disposal.
1.2.3 Precision and Survey Antenna
The Precision GPS/GNSS/L-Band, GPS/Beacon, or GNSS Survey antenna
supplied with the SXblue Series have been designed to provide reliable, stable
and consistent sub-meter and centimeter positioning. The GPS/GNSS/L-Band
antenna feature a female SMA connector, whereas the GPS/Beacon and GNSS
Survey antenna feature a TNC female connector (see Figure 1-3). The bottom part
of the GPS/GNSS/L-Band antenna is magnetic and can be detached by removing
the 4 screws. Magnetic mount is optional for the GPS/Beacon and GNSS Survey
antenna.
Using different antenna than the ones supplied, might degrade the performance of
the SXblue receiver. Shall a different antenna be used, a maximum of 29dB gain
is recommended. When using longer antenna cable, it is important to take into
account the cable loss (dB/m) to allow at least 21dB at the RF input of the receiver.
