Operation Manual

English
The iSongBook may be used with the AC adapter exclusively without batteries installed.
The LCD will show battery strength whenever the iSongBook is on and batteries are installed.
The battery strength meter is approximate. Three bars represent full strength, two bars represent
roughly 50% strength, and one bar represents about 25% remaining strength. The signal strength
meter will not be shown when there are no batteries installed and the iSongBook is operating
from the power supply.
Figure 11
An “E” (“Empty”) on the LCD represents batteries which are just about depleted and should be
replaced if Alkaline, or charged if NiMH/NiCAD, within approximately 10 minutes or the display will
go blank and all memory settings will be lost(Figure 11). If the display shows “E” and alkaline
batteries are replaced while the iSongBook is On, the “E” will reappear on the LCD after the
batteries are replaced until the unit is switched Off and then turned back On to reset the micro-
processor. Batteries should be replaced with the iSongBook Off.
Other Important Battery Notes:
•Rechargeable batteries that are brand new, or have not been used in a long time, require
conditioning (5–6 full charge/discharge cycles) before lengthy playback time is realized.
Higher mA valves will yield longer playback time but will also require a longer charge time.
