SmallTalk ST2-SR user instructions
The SmallTalk ST2-SR is a communication accessory for the Sundström half
masks and full face respirators. When used in accordance with these instructions,
the respirator continues to provide full protection.
To t battery (g. A):
● Remove the battery cover by pressing down and sliding it out of the unit.
● Insert a 9V battery, with polarity as per markings inside battery compartment.
● While holding the battery in place, slide battery cover back in place.
To attach SmallTalk to the respirator (g B):
● Remove the exhalation valve cover from the exhalation valve on the right hand side of the
mask.
● Remove the exhalation membrane. Keep in a safe place for future use.
● HALF MASK: Fit the microphone holder over the rim of the exhalation seat, with the cable
pointing downwards toward the ‘chin’ of the respirator (g. C).
● FULL FACE MASK: Detach the head harness and neck band buckles. Thread the slot in the
lug of the microphone holder over the triangular harness attachment lip. Fit the microphone
holder over the rim of the exhalation seat, with the cable pointing towards the ‘chin’ of the
respirator. Reattach the head harness and neck strap (g. D).
● Attach the cable clip to the nametag holder of the mask and make sure the cable is securely
fastened to the clip (g. C, D).
● Don the respirator and clip the SmallTalk ST2-SR to your pocket, waistbelt or onto the
optional belt clip (g. E).
● Switch on the SmallTalk ST2-SR and adjust the volume to the desired level.
IMPORTANT: Before commencing work in a contaminated atmosphere, perform a leakage test
according to the respirator instruction manual (place the pre-lter holder to the lter; t the
mask; place the palm of your hand lightly over the hole on the pre-lter holder; breathe in and
hold your breath. The mask should press against your face for as long as you hold your breath.
If the vacuum disappears quickly, there is a leakage problem that needs to be rectied) (g. F).
REMOVAL: If you do not wish to use SmallTalk anymore, remove the device from the respirator
and replace the original membrane and valve cover. You MUST perform a leakage test before
using the respirator again (see ‘IMPORTANT’ above).
Cleaning and maintenance:
● The SmallTalk ST2-SR is water resistant. However, do not subject it to running water, and
do not immerse it in water.
● Wipe the loudspeaker with clean, damp cloth. Do not use solvents.
● Avoid exposing the microphone to water. Wipe with clean, damp cloth. Do not block vent
holes on the microphone housing.
● If unit accidentally comes into contact with water; remove battery; wipe it; shake out any
water inside battery compartment. Let air dry.
