Remark
Section 1 – General Information
About KTMED Monitor
ANGELUS displays numerical values for functional arterial hemoglobin oxygen saturation
(SpO2) in percentage, pulse rate in beats per minute and NIBP on light emitting diode
(LED) digital displays
You can expect outstanding monitoring performance with Angelus during a surgery or
intensive monitoring care
The monitor is powered by AC Power or by a rechargeable battery pack.
A battery was added to enable the monitor to be used if there is a power outage or to be
unplugged momentarily when moved with the patient from the surgery room to the
recovery room. The ANGELUS monitor should be plugged into AC as much as possible to
give you the maximum battery backup time when there is a power outage. It will maintain
unit operation

„
„
„
„
„
„
„
„
„
Use a grounded wrist strap before starting the assembly and disassembly of the
monitor.
The monitor could be damaged by water and liquid. Do not repair the unit where
water or liquid falls on.
Do not remove the battery during charging
The battery is consumable parts and when purchasing, compared
The use hour is gradually decreases.
The recharging time depends on the voltage level and ambient temperature of the
dry cell.
Do not immerse the monitor in any fluid
Do not dispose of the battery in the regular waste collection.
Do not operate the monitor unless it has been calibrated properly
The monitor does not operate effectively if a patient is having seizure activity
In shock conditions, the low amplitude of the blood pressure waveform may make
it difficult for this monitor to accurately determine the systolic and diastolic
pressures.
NIBP: Accuracy of any blood pressure measurement may be affected by the
position of patient.
All hose and cuffs used to the patient should be approved by KTMED.
Incorrect size or incorrect fitting may be result in the incorrect readings.
WARNING
Service personnel might be electrically shocked or parts might be damaged when repairing
the ANGELUS.
Before repairing, service personnel should follow to;
„
„
„
„
„
„
„
Disconnect the AC power.
Remove internal battery.
Antistatic himself.
Read this manual carefully.
To ensure safety, use only accessories & parts recommended or supplied by
KTMED
Always follow the manufacture’s instruction.
Unauthorized repairs will void the warranty.

Section 2 – Functional Tests and Trouble Shooting
Functional Tests
Check 1: Power
After connect to AC power cord, and than AC power switch on, check the AC LED in
keypad of front panel. If AC LED light on, check 1 is OK. If AC LED light off, check 1 is
fail.
Check 2: Power Cord
If there are open wiring on AC power cord. Change the power cord.
Check 3: Fuse
After identify there aren’t any problems on check 2, if AC LED light off, check the fuses
in AC inlet. If fuse is broken, replace the fuses.
We can find it’s faulty by see with eye but if you can’t, you may use resister. If the
measurement of it’s register below some Ω, there aren’t any faulty but over some KΩ,
replace fuses to new one.
Check 4: Charge
Check the BATT LED in keypad of front panel. If BATT LED light on, check 4 is OK. If
BATT LED light off, check 4 is fail. In case of, you have to replace Power Board.
Check 5: Discharge
After battery charge enough, it will maintain about 1 hour normal operation, the battery is
no problems. However within 40 minutes, if you can find this case, you are needed to
replace the battery.
