Powering Your Scanner
Using Batteries
Your scanner has a built-in charging circuit to maintain
peakperformanceofyourNickel-MetalHydride(Ni-MH)
orNickelCadmium(Ni-CD)rechargeablebatteries(not

blackholder;forrechargeablebatteries,usethe
yellow holder.
3. Place the battery holder into the battery
compartment and replace the cover.
Warning: Never install non-rechargeable batteries in the
rechargeable yellow battery holder. Non-rechargeable

Cautions:
Thebatteryholderstonlyoneway.Donotforcethem.
Use only fresh batteries of the required size and
recommended type.
Remove old or weak batteries. Batteries can leak
chemicals that destroy electronic circuits.
Disposeofoldbatteriespromptlyandproperly.Donot
burn or bury them.
Donotmixoldandnewbatteries,dierenttypesof
batteries(alkaline,orrechargeable),orrechargeable
batteriesofdierentcapacities.
If you do not plan to use the scanner with batteries for a
monthorlonger,removethebatteries.Batteriescanleak
chemicals that can destroy electronic parts.
Using AC Power
Connect a compatible adapter to the scanner’s DC 9V
jackandastandardpoweroutlet.Todisconnect,unplug
theadapterrst.
Caution: You must use a Class 2 power source that
supplies9VDCanddeliversatleast400mA.Itscentertip
mustbesettopositiveanditsplugmusttthescanner’s
DC 9Vjack.Usinganadapterthatdoesnotmeetthese
specicationscoulddamagethescannerortheadapter.
Note: If you use a cigarette-lighter power cable and your
vehicle’sengineisrunning,youmighthearelectrical
noise from the engine while scanning. This is normal.
Turning on the Scanner
1. Turn the SQUELCH all the way down before you turn
