Caution
• Use the Image Sync app to make the Bluetooth and WiFi
handshakes; this seems to result in better reconnections. If
already paired/connected, just ’unpair’ and/or ‘forget’ the
connections in the phone’s settings. Up to six devices can be
paired to the camera.
On the camera, turn on geotagging:
1. Menu button
2. Setup
3. Communication Settings [4]
4. Smartphone Link
5. Store Location Info.
6. On
7. OK
On the camera, enter pairing mode:
1. Menu button
2. Setup
3. Communication Settings [4]
4. Bluetooth Setting
5. Action Mode
6. On
7. OK
8. Pairing
9. Execute Pairing
On the phone, connect the camera:
1. Start Image Sync
2. Select ‘Cam images’
3. Select ‘PENTAX K-3 Mark III’
4. Select ‘Connect over Bluetooth’
5. Enter ‘XXXXXX’ from the camera info screen
6. Select ‘Next’
7. Wait for popup, enter ‘######’ Authentication code from
the camera info screen
8. Select ‘Pair’, if the phone popup asks to Connect to Device,
select ‘Connect’
9. The camera and phone automatically attempt to connect
via WiFi. No need to enter the WiFi password. The phone
may popup a confirmation message.
On the phone, configure Image Sync:
1. Confirm ‘Automatic Bluetooth connection’ is enabled in
‘Settings’.
2. Turn on geotagging: select ‘Settings’ and enable ‘Store
location information’.
3. Turn on background use: Select ‘Settings', then
‘Background location information transmission’ and enable
it for ‘No time limit'.
You have now paired (Bluetooth) the camera and phone, and
connected the camera and phone via WiFi, which allows
viewing and downloading files. It also allows controlling the
shutter, etc. with live view.
Caution
• Since Image Sync will always require WiFi to reconnect, turn
off ‘Auto reconnect’ in the phone’s settings under
Advanced, when not WiFi connected. For Android 11:
Settings | Connections | WiFi | 3dotmenu | Advanced |
Manage networks | select the WiFi name from the camera
info | unselect Auto reconnect
Memo
• See Power Off and Auto Off (Sleep) Behavior below.

If the camera Bluetooth is on (and camera WiFi is off) you can
connect by using the saved pairing information and the
camera will turn on WiFi and connect with full control, then
disconnect Bluetooth.

Bluetooth icon)
2. Start Image Sync
3. Select ‘Cam images’

and connects to the phone (may get confirmation popup),
then Bluetooth is disconnected. If the camera and phone are
already connected via WiFi, Image Sync will disconnect and

ask for the camera model. In which case, after selecting ‘Cam
images’ above:
4. Select ‘PENTAX K-3 Mark III’
5. Select ‘Connect to PENTAX_XXXXXX’ if using Bluetooth
or select ‘Connect over Wi-Fi’ if WiFi is already connected
(white WiFi icon)
