Keeping distance between leads
Connecting the lead connector to the device
Applying the programming head
The programming head (PGH) features a diagram of the device. This is used to assist in
positioning the head to ensure proper telemetry.
• Make sure the PGH is positioned correctly.
Establishing telemetry contact
The programmer (or the SafeSync Module) can be no less than 20 cm and no more than
3 m from the device; ideally there should be no hindrances between the patient and the
programmer.
• Switch on RF telemetry on the programmer.
• Apply the programming head for about 2 s until successful initialization is displayed
on the programmer:
The SafeSync symbol is displayed in the navigator and the signal strength
is displayed in the status line.
• Remove the programming head.
Auto-initialization
Auto-initialization begins automatically once the first connected lead is sensed.
Auto-initialization is terminated 10 minutes after connection of the first lead. If no other
program has been transferred in the meantime, the device subsequently works with
active automatic functions in the factory settings or with the preset program of the
user.
Manual setting of the lead polarity or measurement of lead impedances is not neces-
sary.
Behavior during auto-initialization
• During transmission of a permanent program:
Auto-initialization is terminated and the transferred program is active.
• During testing:
Tests cannot be performed during auto-initialization; stop it beforehand.
Auto-initialization will not be continued upon completion of the test.
Precautionary Measures while Programming
Checking the device system
• After auto-initialization, perform a follow-up to see if the device system is func-
tioning properly.
• Perform a pacing threshold test to determine the pacing threshold.

WARNING
Inadequate therapy
Insufficient lead spacing or inappropriate lead positioning may lead to far field
sensing.
• Tip and ring electrodes must not have contact with each other.
1
Disconnect stylets and stylet guides.
2
• Connect the unipolar or bipolar IS-1 lead connector ventricle to RV.
• Connect the unipolar or bipolar IS-1 lead connector atrium to A.
• Connect the unipolar or bipolar IS-1 lead connector ventricle to LV.
3
Push the lead connector into the header without bending the conductor until the
connector tip becomes visible behind the set screw block.
4
If the lead connector cannot be inserted completely, the set screw may be
protruding into the drill hole of the set screw block. Carefully loosen the set
screw without completely unscrewing it, so that it does not become tilted upon
retightening.
5
Use the screwdriver to perpendicularly pierce through the slitting in the center
of the silicone plug until it reaches the set screw.
6
Turn the set screw clockwise until the torque control starts (you will hear
a clicking sound).
7
Carefully withdraw the screwdriver without retracting the set screw.
• When the screwdriver is withdrawn, the silicone plug automatically seals the
lead connection safely.
Note:
After auto-initialization, all parameters are activated as in the factory settings.
