Garmin Forerunner 935 Benutzeranleitung

After you put on the heart rate monitor, it is active, storing, and 

sending data.

• Adjust the tightness of the heart rate monitor and strap 

extender if the heart rate monitor slides down your chest 

when pushing off the pool wall.

• Stand up between intervals so that the heart rate monitor is 

out of the water to see your heart rate data.

A buildup of sweat and salt on the strap can decrease the ability 

of the heart rate monitor to report accurate data.
• Rinse the heart rate monitor after every use.
• Hand wash the heart rate monitor after every seven uses, 

using a tiny amount of mild detergent, such as dishwashing 

liquid.
NOTE: Using too much detergent may damage the heart rate 

monitor.

• Do not put the heart rate monitor in a washing machine or 

dryer.

• When drying the heart rate monitor, hang it up or lay it flat.

The HRM-Swim section of this manual explains recording heart 

rate during your swim (

).

Hand wash the heart rate monitor after exposure to chlorine or 

other pool chemicals. Prolonged exposure to these substances 

can damage the heart rate monitor.
The HRM-Tri accessory is designed primarily for open water 

swimming, but it can be used occasionally for pool swimming. 

The heart rate monitor should be worn under a swim suit or 

triathlon top during pool swimming. Otherwise, it may slide down 

your chest when pushing off the pool wall.

You should wear the heart rate monitor directly on your skin, just 

below your sternum. It should be snug enough to stay in place 

during your activity.

If necessary, attach the strap extender to the heart rate 

monitor.

Wet the electrodes 

À

 on the back of the heart rate monitor to 

create a strong connection between your chest and the 

transmitter.

Wear the heart rate monitor with the Garmin logo facing right-

side up.

The loop 

Á

 and hook 

Â

 connection should be on your right 

side.

Wrap the heart rate monitor around your chest, and connect 

the strap hook to the loop.
NOTE: Make sure the care tag does not fold over.

After you put on the heart rate monitor, it is active and sending 

data.

The heart rate monitor can store up to 20 hours of data in a 

single activity. When the heart rate monitor memory is full, your 

oldest data is overwritten.
You can start a timed activity on your paired Forerunner device, 

and the heart rate monitor records your heart rate data even if 

you move away from your device. For example, you can record 

heart rate data during fitness activities or team sports where 

watches cannot be worn. Your heart rate monitor automatically 

sends your stored heart rate data to your Forerunner device 

when you save your activity. Your heart rate monitor must be 

active and within range (3 m) of the device while data is 

uploaded.

A buildup of sweat and salt on the strap can decrease the ability 

of the heart rate monitor to report accurate data.
• Rinse the heart rate monitor after every use.
• Hand wash the heart rate monitor after every seven uses or 

one pool swim, using a tiny amount of mild detergent, such 

as dishwashing liquid.
NOTE: Using too much detergent may damage the heart rate 

monitor.

• Do not put the heart rate monitor in a washing machine or 

dryer.

• When drying the heart rate monitor, hang it up or lay it flat.

If the heart rate data is erratic or does not appear, you can try 

these tips.
• Reapply water to the electrodes and contact patches (if 

applicable).

• Tighten the strap on your chest.
• Warm up for 5 to 10 minutes.
• Follow the care instructions (

).

• Wear a cotton shirt or thoroughly wet both sides of the strap.

Synthetic fabrics that rub or flap against the heart rate 

monitor can create static electricity that interferes with heart 

rate signals.

• Move away from sources that can interfere with your heart 

rate monitor.
Sources of interference may include strong electromagnetic 

fields, some 2.4 GHz wireless sensors, high-voltage power 

lines, electric motors, ovens, microwave ovens, 2.4 GHz 

cordless phones, and wireless LAN access points.

You can use your compatible Forerunner device paired with the 

HRM-Tri accessory or other running dynamics accessory to 

provide real-time feedback about your running form. If your 

Forerunner device was packaged with the HRM-Tri accessory, 

the devices are already paired.
The running dynamics accessory has an accelerometer that 

measures torso movement in order to calculate six running 

metrics.
Cadence: Cadence is the number of steps per minute. It 

displays the total steps (right and left combined).
