Supplying Power
The SDA 601 is DC powered. You may power it with the standard AC

and install the pack properly.
When selecting a power source for your SDA 601, please remember:
HAttempting to use an improper AC adapter can cause permanent
damage to the instrument. USE AN APPROPRIATE DC POWER
SOURCE ONLY: Voltage must be between 9 and 15 VDC; the
center contact of the connector must be NEGATIVE polarity; and
open-circuit voltage must not exceed 18 VDC. For best results, use
the adapter supplied with the instrument.
HThere is no need to remove the optional NiCad battery pack for
recharging. The SDA601 will “trickle charge” the battery pack
whenever the standard AC adapter is attached and the instrument
