Image Sync Functions and Limitations .

Requires WiFi to view or download files from camera (i.e.,

using the ‘Cam images’ button)

• Cannot connect Bluetooth and WiFi simultaneously; will

switch back and forth depending on functions/options

selected

• Geotagging works with Bluetooth or WiFi, although WiFi

geotagging requires the phone be awake and Image Sync to

be the active app

• WiFi is required to view scene in control mode live view;

Bluetooth will control camera, but cannot use live view

• When connected with Bluetooth, can turn on WiFi

connection in camera for full control

• For Bluetooth geotagging, Image Sync must me running, but

need not be the active app, if background transmission is

enabled

First Time Pairing/Connecting .

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:

Manage networks | select the WiFi name from the camera

info | unselect Auto reconnect

Memo

• See Power Off and Auto Off (Sleep) Behavior below.

After First Time Pairing/Connecting .

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.

Normal:

1. Turn on the camera and ensure Bluetooth is enabled (gray

Bluetooth icon)

2. Start Image Sync

3. Select ‘Cam images’

Bluetooth is connected and WiFi is activated on the camera

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

reconnect via WiFi (may get confirmation popup).

Abnormal:

If Image Sync does not automatically find the Camera, it may

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)
