• Should you reach a maximum or minimum value, kVp / mAs MAX or kVp / mAs 
MIN will briefly appear on the message display to alert you. 
IMPORTANT!:Carefully check the digital display (see Illustration 5-9) before making an 
exposure to ensure that the factors selected are those that are intended. 
Pay particular attention to the placement of the decimal point in the mAs 
setting to ensure that whole...

5-7 Taking Exposures
Check the battery status and message displays for battery condition. Its 
important to note that you do not have to raise your kVp or mAs value to 
compensate for low battery voltage.
Steps
Once youve positioned patient and cassette, selected technique and the proper 
safety precautions are taken, follow these steps.
1 Remove handswitch from saddle. Press the handswitch button half way...

CHARGING THE BATTERIES/CAPACITY GAUGE OPERATION
Overview
Battery charging is as easy as driving the AMX-4+ to a correctly rated wall outlet  
and plugging the unit in. Ratings are as follows:
• For Models 2169360-7,-8,-9,-10, 2236420-7,-8,-9,-10, 2275938-7,-8,-9,-10: 
120 Volts AC, 60 Hz at 6A.
• For Models 2169360, 2169360-2,-3,-4, 2236420, 2236420-2,-3,-4, 2275938,...

ILLUSTRATION 6-1 
The blue battery status display approximates remaining battery charge, and should 
only be used to gather information as to the relative state of charge.
As the AMX-4+ is used in its various modes of operation, the number of segments lit 
will slowly decrease.
Its important to note that you do not have to raise your kVp and mAs value to 
compensate for low battery voltage.
Should the...

ILLUSTRATION 6-2 
As Illustration 6-2 demonstrates, the majority of the battery packs capacity is 
used for drive and idle.  Thus, reducing the amount of drive time by parking the 
AMX-4+ in a central location and turning the system OFF when not in use will 
make more capacity available for X-ray generation and will increase the service 
life of the batteries.
Note:See the Ratings and Specification Section,...

Capacity Gauge Features
“STUCK AT FULL” FEATURE
After the AMX-4+ charges to 100% (i.e. “CHARGE COMPLETE” ), the capacity gauge 
will remain “stuck-at-full” for a pre-programmed amount of usage before the 
number of lit segments begins to decrease.   This usage is equivalent to 
approximately 10 minutes of drive or 100 minutes of idle.   Once this “stuck-at-full” 
capacity is used, the capacity gauge will...

are disabled. Note that you may charge the batteries with the KEYSWITCH in 
either the ON or OFF position.

MAINTENANCE AND SERVICE
7-1 Cleaning the Unit
We recommend that you clean the AMX-4+ regularly with a soft cloth and a mild, 
non-abrasive cleaner. Apply the cleaner to the cloth, not directly to the unit , to 
safeguard against damage to the circuitry. If a corrosive chemical is spilled or 
splashed on the unit surface, be sure to clean it off immediately. 
7-2 Hand Switch Cleaning and...

7-3 Main Power Circuit Breaker
The main power circuit breaker is located on the front right side of the unit . Refer 
to Illustration 6-3.
If the battery charge is too low, or in the event of an overload in the high-voltage 
system, the circuit breaker will trip (interrupt power to the X-ray unit). 
Should the circuit breaker trip, the control panel lights will go out and youll be 
prevented from operating...
