To begin using the Spectra immediately, use the back-up “AA” battery pack (Blue Decal).
• The standard battery holder (Blue Decal) holds eight “AA” cell batteries. Alkaline batteries are recommended for
use with this battery holder.
• Non-alkaline batteries can be used in this holder. When non-alkaline or rechargeable “AA” cells are used, detecting
time (before replacement/recharge) may be reduced or increased depending upon the type of battery used.
• An ” Unhappy Battery Icon” will automatically appear on the display (lower left status line) when the
batteries become too low (8 volts) to properly operate the Spectra.
• A headphone icon with a battery inside indicates the batteries are low in the wireless headphone. See additional
status indications on bottom of control box.
• The battery compartment opens by gently pulling down on the front of each of the two latches (on the bottom of the
control box) releasing the catch and hinging open the door. The non-rechargeable battery holder can use many different types
of batteries, including rechargeable. This holder is designed for standard size “AA” batteries 50 mm ± .10 mm. Battery lengths
shorter than this will likely cause problems with this power supply.
• When the Spectra is turned on the battery voltage will momentarily appear on the opening display (lower left). The
degree the battery is fi lled, , indicates the battery condition. Full Fill = 100% battery life remaining, half fi ll = 50%
battery life remaining.
• To recheck the battery voltage during searching, press MENU twice and note battery voltage under BATTERY.
Spectra operates correctly between 8 Volts “low battery” and 13 Volts. Squeeze and release Trigger on grip (twice) to return
to searching. Initial battery check voltage may indicate abnormally high. With new Alkaline, or a fresh battery charge, the
most accurate battery voltage will be indicated after one hour of use.
Batteries
The Spectra is provided with two battery packs. The rechargeable Nickel Metal
Hydride (NiMH) battery (Orange Decal) will require an initial 3-4 hour battery
charge.
