Appendix A. Notice to Installers / Caregivers
Rechargeable Battery
Your MD.2 is shipped with a rechargeable battery installed and partially charged.
Once the MD.2 is connected to its normal power source, it should take no more
than 36 hours to fully charge the battery. Note the caregiver can examine the
charge capacity of the battery at any time by pressing the Status button on the
MD.2. The battery should provide 3 or more years of trouble free service under
normal power backup operations (occasion battery use during power outages). An
excessive number of discharge/charge cycles will reduce battery life.
Battery Maintenance
No maintenance is required during normal operation of the MD.2. If the MD.2 is
to be stored for an extended period of time however, Interactive Medical
Developments, LC. recommends for optimal performance and battery life:
• The MD.2 be plugged in for a minimum of 36 hours once every 6 months
to replenish battery charge.
• The MD.2 not be stored at elevated temperatures for any extended period
of time.
Battery Capabilities
With the rechargeable battery supplied with your MD.2, the MD.2 will typically
run for 9 hours on battery power. Once power is restored, it will take
approximately 48 hours to recharge fully discharged batteries.
