Question: What does this use for memory backup?
Answer: The PRO-70 does not have an internal battery. The memory backup is an RC circuit and keeps the channel frequencies stored in
memory for about 1 hour during a power loss.

Product: PRO-79 200 Channel Handheld Scanner Cat. No.: 200-0314
Question: Page 10 of the user's manual states that you must recharge high-capacity Ni-Cd batteries in an external charger and that "You
cannot use a DC adapter to recharge batteries in the scanner due to limitations in the scanner's recharging circuit"... What exactly are these
limitations and why can't I charge high-capacity Ni-Cd batteries?
Answer: We do not recommend that you use the DC adapter for charging because the DC from a vehicle tends to have voltage fluctuations and
noise in the signal. When charging, these fluctuations and noise can cause the battery to not take a charge as well and lessens the battery's
capacity and effective life span. The charging circuit is not designed to compensate for these problems, so it should only be used with an AC
adapter. Standard life Ni-Cd's take 14 to 16 hours to recharge in the internal charger; this charger is not designed to charge for the extended
period required for high capacity batteries. Using it in this way can damage the internal charger, the batteries or both.

Product: PRO-90 300-Channel TrunkTracker Scanner Cat. No.: 200-0520
Question: The scanner battery life has dropped to about 20 min; how can I fix this?
Answer: We recommend that you deep cycle the battery (fully discharge, then fully recharge the battery). It may have developed a memory; you
may have to do this more than once to return to normal functionality.
