Installing and Removing a Battery
See “Specifications” on page 247 for acceptable batteries.
Note: Battery service life can be substantially improved by using nine-volt lithium
batteries.
To install a 9V transceiver battery, first open the transceiver battery compartment by
placing your thumb and forefinger on the compartment latch and flipping it open.
Inspect the battery compartment and insure that there is no foreign object present that
could block the battery contact or short the battery terminals. Next, place a 9V battery
inside the compartment with the prongs touching the compartment contacts. The ori-
entation of the battery prongs against the contacts does not matter, so long as the
prongs and contacts are touching. Finally, close the battery compartment door by
pressing it until the latch clicks into place and the compartment is secure.
To remove a battery, simply follow the installation steps listed above and discard the
used battery per applicable regulations.
Warnings
1. ECG lead wires must be dressed and secured to the patient to prevent the
possibility of them encircling the patient’s neck and causing strangula-
tion.
2. When installing or replacing the battery, visually inspect the battery
compartment and ensure that there are no foreign objects inside. A con-
ductive object making contact with the battery contacts could cause the
battery and battery compartment to overheat, resulting in burns to the
patient and to the attendant removing the battery.
3. A foreign object blocking battery contact with the DT-4500 could prevent
its operation resulting in failure to monitor the patient.
4. Always perform a battery check procedure after installing or replacing
the battery.
5. Lithium Batteries may explode if mistreated. DO NOT recharge, disas-
semble, or dispose of batteries in fire.
Cautions
1. Transceivers should be carried securely in pouches or in a pocket of a
patient’s gown. If the weight of the transceiver pulls on the wires, then
the wires can be damaged or worn
2. Make sure that the wires are not twisted around each other; since, this
can interfere with transmission and produce noise.
3. Make sure that the lead wires are not inadvertently pinched in the bed
rails. This may cut the insulation or break the leadset.
