Battery Level Indicator
NOTE: Valid for portable ZK-SAMp. A battery icon is used to indicate the
current storage level of the main battery. The unit will power down when
the battery has only five-percent charge remaining.
When the battery goes below 20 percent chargeit will beep five times every
two minutes. Replace the battery with a fully charged one.
Performance Tip: A fully charged battery (two hours of charging time) typ-
ically provides five to seven hours of operation. To increase the battery life,
set the backlight to its lowest setting.
Memory Indicator
An icon is used to indicate the amount of free memory on the Compact
Flash card for data. When memory is full the data will be overwritten on a
first in - first out (FIFO) basis.
The amount of data stored is dependent on the disk space of the compact
flash card. Typically, up to 5MB of data per CDMA phone and up to 7MB
per GSM phone can be stored per hour.
Markers
Pressing the ENTER key inserts a marker into the data file for post-
processing. When a marker is entered, the “Pushpin” icon will be displayed
with the number of the marker next to it.
Time with GPS Available
The Time indicator appears on every screen. Units with GPS will display a
circle and, in the lower portion of the screen, the number of locked-in satel-
lites.
The time is generated by an internal clock backed up by an internal lithium
battery. The average lifespan of the internal battery is ten years and must be
replaced by a factory-authorized technician.
For units with GPS receivers the internal clock is updated by GPS time (if
there is a current fix) each time the user goes into and out of the SAM-
ALL.
