WARNING:
Do not cut open, incinerate, heat above 85°C
(185°F), or recharge the lithium batteries. The batteries may
explode if the logger is exposed to extreme heat or conditions
that could damage or destroy the battery cases. Do not mix
battery types, either by chemistry or age; batteries may rupture
or explode. Do not dispose of the logger or batteries in fire. Do
not expose the contents of the batteries to water. Dispose of
the batteries according to local regulations for lithium
batteries.
To replace the batteries:
1.
Open the station door.
2.
Disconnect the battery cable.
3.
Use a flat-head screwdriver to remove the screw below the
battery cover.
4.
Pull to remove the battery cover.
5.
Remove the old batteries.
6.
Install six new batteries observing polarity.
7.
Reinstall the battery cover.
8.
Use a flat-head screwdriver to secure the cover with the
screw.
9.
Plug in the battery cable.
Battery Information for the RX2106 Model
The RX2106 station uses one rechargeable NiMH battery pack
(HRB-NiMH-6). Typical battery life is 3–5 years when operated
in the temperature range -20° to 40°C (-4° to 104°F); operation
outside this range will reduce the battery service life. Use the
AC adapter (P-AC-1), built-in solar panel, or external solar panel
(SOLAR-xW) to keep the battery charged. If using an external
solar panel or built-in solar panel, the quality and quantity of
solar light can affect whether the battery is sufficiently charged
to last through the night and cloudy periods.
The maximum connection rates when using the built-in solar
panel in full sun are:
•
10 minute connections year round for latitudes less than
±40°
•
10 minute connections through three seasons in other
regions, reduced to 30 minute connections in winter
The maximum connection rate when using an external 5W or
15W solar panel is 10 minute connections year round, in full
sun. The connection rate with external solar panels may be less
if deployed in partial sun.
Battery life for the RX2106 model is 1 month without solar
recharging, with hourly connections, a 1-minute logging
interval, and approximately 10 motes.
Deployments in extremely cold or hot temperatures, a logging
interval faster than 1 minute, or a sampling interval faster than
15 seconds can impact battery life. Estimates are not
guaranteed due to uncertainties in initial battery conditions and
operating environment. If using an external solar panel or built-
in solar panel, the quality and quantity of solar light can affect
whether the battery is sufficiently charged to last through the
night and cloudy periods
The station will shut down once the battery voltage drops to 6
V. Plug in an AC adapter or solar panel to recharge it. Once the
voltage rises to 7.5 V, the station will power up. If the charging
device is not recharging a dead battery, contact Onset Technical
Support.
To replace the battery pack:
1.
Open the station door.
2.
Disconnect the battery cable.
3.
Use a flat-head screwdriver to remove the screw below the
battery cover.
4.
Pull to remove the battery cover.
5.
Remove the old battery pack and install the new one from
Onset.
6.
Reinstall the battery cover.
7.
Use a flat-head screwdriver to secure the cover with the
screw.
8.
Plug in the battery cable.
9.
Make sure the built-in solar panel cable is plugged in. If you
are using an external solar panel, make sure the built-in
solar panel cable is tucked inside the station door. Plug in
the external solar panel. Lightly coat the portion of the
cable that will be placed in the cable channel with a small
amount of silicone grease. Route the cable through the far-
left hole in the cable channel.
WARNING:
Dispose of the battery pack according to local
regulations for NiMH batteries.
