d) Pacemaker and other implanted
devices may change the electrical
characteristics and operation of heart
so that transmitter detects several

signal compared to normal a ECG
signal possibly causing a transmitter
to send two pulses for each heart
beat. Please turn transmitter upside-
down.
f) Interferences. Electrical equipment
such as monitors, motors, LED
displays, transformers switches,
cellular phones and etc. generate
electromagnetic noise which may
cause missing or extra pulses
resulting in incorrect heart rate reading
