DESCRIPTION
The RTP- !002A is a battery pack and charger
designed to be mounted to the back of the R-2001 Com-
munications System Analyzer. The unit contains battery
capacity to operate the R-2001 for approximately one
hour. A constant current charging system is capable of
recharging the batteries in 16 hours.

OPERATION
2.1
The RTP-1002A Battery Pack is automatically
engaged when no ac power is present, and the
power switch is either in the ON or STANDBY posi-
tions. When ac power is applied, the R-2001 auto-
matically switches the RTP-1002A Battery Pack out of
the circuit and draws its power from the ac power
source.
2.2
When the power switch is in the OF.F or STAND-
BY position and ac power is applied to the
R-2001, the RTP-1002A Battery Pack draws de current
from the R-2001 to activate the charging circuit. The
charging circuit delivers approximately 750 mA of cur-
rent until the battery voltage reaches 14 volts. As the
\

battery voltage reaches 14 volts, the current drops to ap-
proximately 25 rnA and the high-charge indicator LED
extinguishes.
2.3
When the R-2001 systems analyzer is used with the
RTP-1002A Battery Pack, it is recommended to
keep the power switch in the STAND BY position
whenever possible. This extends the time the battery is
able to operate the R-2001 Communications System
Analyzer. The low trickle charge rate enables the bat-
teries to be left on charge indefinitely without damage
due to overcharging.
CAUTION
Do NOT permit battery discharge below
I 0.4 V de as indicated on CRT in DVM
display mode; immediately turn unit
"OFF".
Allowing
battery
discharge
below this level may result in permanent
damage to the battery. The R-2001 should
be plugged into ac power (117/234 V ac)
with the power switch in "OFF" or
"STANDBY" position to recharge the
batteries.
