Battery Charging - Horizon Fitness HD-S2 User Manual

Battery Charging

The meter will NOT be fully charged when you receive it. We recommend you charge it for an initial 8 hours
before use. If your meter is not being used for a long period of time, we recommend disconnecting the battery.
You can also top up your battery from your vehicle with the in car DC Adapter supplied. You should top up the
charge every 2 weeks. The battery pack is replaceable, but it should only be removed or disconnected in the
event of a failure. Please see page 25 for battery removal.
1.5A
For in-vehicle charging only use the lead supplied. The use of another lead may damage the meter and will void
the warranty. The HD-S2 can remain connected to either power source in "Trickle" charge state for an extended
period of time. Once "Charge Complete" appears on the display the HD-S2 will be in a trickle charge state.
Note: When charging your battery HD-S2 Li-Po battery please ensure that the ambient temperature is above
freezing point 0º C (32º F) and not above 40º C (100º F) this will prevent damage to your battery pack.
Note: The meter will not operate while the unit is being charged.
The Li-Po battery pack is replaceable. Always handle the battery with care avoiding shock or impact.
Remove the HD-S2 from its carry case, and on the underside of the meter release the two catches and detach
the battery door. Press the battery down at the end closest to the connector (this will cause the battery
to pop up at the bottom). Now cover the battery with your hand and turn the meter over so that you catch the
battery. Carefully detach the battery connector. You can now fit your replacement battery in the reverse order
of removal.
Note: Avoid pulling the battery cable as it is short to ensure a snug fit.

Charging with the AC lead
On the bottom of the case there is a small velcro
flap which covers the AC input for charging.
Charging from a vehicle
The vehicle 12V DC charge port is on the right side of the unit.
Plug the car charger lead into the bottom socket and the other end
to the vehicle's "aux" socket. Please note that on certain vehicles the
aux socket is switched off unless the vehicle is running.
Note: Do not charge from a vehicle with a
higher battery voltage or positive ground!
