Changing the Speaker Membrane
G8's speaker membrane may accumulate dust and debris, affecting the clarity of incoming audio. Blackline Safety recommends changing the speaker membrane to ensure G8 remains in good working condition.
To change the G8's speaker membrane, you need the following:
Spudger pry tool
Replacement speaker membrane
Replacement speaker grille
Small vacuum or Q-tip with isopropyl alcohol
Note: The speaker membrane replacement kit (ACC-G8-MSFK-XXX) also contains a mic membrane replacement kit. It is recommended to change the speaker membrane and mic membrane at the same time. For details, see Changing the Mic Membrane.
CAUTION: G8 must be powered off for this procedure. Otherwise, the device may send out false alerts.
- Pull down the red latch to expose the speaker grille.
- Place the flat end of the Spudger pry tool beneath the speaker grille, then lift the grille to remove it.
- Use the tool to remove the existing speaker membrane.Note: The speaker membrane may be attached to the speaker grille and come off when you remove the grille.
- Place the new membrane into the designated slot. Ensure the black side of the membrane is facing outward.
- Get a new speaker grille from the replacement kit.
- Insert the new grille into the designated slot under the G8's middle button. Note: The top of the speaker grille has ridges and should be inserted first.
- Press down at the bottom of the grille until you feel it engage.
