Reset the Optik remote and ensure the box's volume is set to max. If the set top box is connected directly to your TV it should work. Do you have anything connected between the TV and set top box like a receiver? What type of cable? HDMI?
If the box is set to Lower Mainland, you'll need to call or possibly chat with Telus to have that corrected. Normally if the set top box is correctly registered to your account it should have the correct region.
