Power Supply
Two disposable AA batteries (industrial AA’s), which you insert into the unit’s battery compartment, are used
to power the Ambulatory X-12. The typical life of two AA batteries is 30 hours.
When you turn the unit on, ON appears on the LCD screen to the lower left of the torso.
NOTE: Alkaline batteries are recommended .
Battery Installation and Ambulatory X-12 Operation
To install the new batteries and operate the Ambulatory X-12:
n Position the Ambulatory X-12 with its back facing you. (See the illustration which follows.)
o Grasp the device with one hand on each side, placing your right and left thumbs on the back’s grooved
sections of the battery compartment. Then gently push your thumbs down and away to remove the battery
compartment.
p Turn the compartment over and insert one new battery in each battery slot. To be sure of correct
placement, align the positive (+) and negative (-) locators of each battery with the respective designator in
each battery slot. (See the previous illustration, “Ambulatory X-12, Back View, with Battery Compartment
Removed.”
q Push the ON/OFF switch, located next to the channel selectors, to the ON position.
r Re-insert the battery compartment.
s When the Ambulatory X-12 is not in use, push the ON/OFF switch to the OFF position.
Note: If the batteries are not functioning, or the ON/OFF switch is in the OFF position, the message ON will
not appear on the LCD screen, and the leads will not flash on the torso.
Ambulatory X-12______________________________________________________________________
2-4
Patient Preparation
Correct electrode placement is important for acquiring a successful ECG (see Patient Hookup below).
Although most resting cardiograms are completely successful without patient preparation, consider performing
some patient preparation procedures to remove oils, lotions, and hair from the skin, particularly on obese
individuals.
Patient Hookup
Figure 2-c Patient Hook-Up
The 12-lead patient cable is attached to the patient, and the patient cable input connector is inserted into the
receptacle located on the right topside of the Ambulatory X-12.
WARNING: QRS morphology may be slightly different from the standard ECG because of different position
of lower limb electrodes. To reduce these differences, try to position LL electrode as low as
possible, e.g., iliac crest, leg root.
Lead Fail
A lead in failure is displayed as a blinking lead designator located on the torso. If the patient cable is not
attached, the LL, V1, V2, V3, V4, V5, and V6 lead designators blink on the torso.
Lead Check
To check the electrode contact quality, you may review the impedance measured for each of the leads. The
Ambulatory X-12 presents this information in the impedance check graph located on the left side of the display
in the triangular box on the left of the LCD. To interpret the impedance check graph, read the instructions on
the back of the Ambulatory X-12.
NOTE: Ambulatory X-12 is not waterproof. Prevent liquid from penetrating, and avoid submerging in any
liquid. Sterilization is not allowed.
The greater the impedance, the more the signal quality is compromised. Increments of impedance are
represented as black bars located within the rectangular box. Six black bars represent minimum impedance, or
optimal signal quality; one bar represents maximum impedance, poor signal quality, or lead fail.
____________________________________________________________________________Section 2
2-5
To check the impedance of each lead:
n Press and hold down the Test key located on the front of the Ambulatory X-12 until the message LC (Lead
Check) appears on the bottom of the display. The LA (left arm) lead designator appears on the upper right
section of the torso. The impedance check graph depicts the value measured for the LA (left arm) lead.
o Press the Call key to check the remaining leads: LL (left arm), V1, V2, V3, V4, V5, V6, RA (right arm).
p To exit the impedance check mode, continue to press the Call key until the LC message is erased.
Once signal quality is confirmed, you are ready to initiate monitoring on the electrocardiograph.
Transmitting
Refer to the appropriate appendix of the Mortara electrocardiograph operator’s manual for setting up the
Wireless Patient Cable.
CAUTION: Failure to properly set up the electrocardiograph with the Ambulatory X-12 Telemetry Module
will result in poor or non-operation of the Ambulatory X-12.
Miscellaneous
Channel Number
The Ambulatory X-12 transmits the patient's cardiac signals to the electrocardiograph using a specific channel
number. The Ambulatory X-12 is preset at the facility with a channel number of 80H. You may, however,
choose individually from any of the 256 channels. If you experience ECG signal loss, for instance, you might
want to change the transmission channel.
The two-channel selector dials are located on the inside of the battery compartment,
